As everyone else has mentioned, EVs and IVs are crucial to online battling. You won't get very far without them and should learn to use them if you intend to keep battling online.
However, there is some other advice I can give you. Play to your team's strengths.
Check your Pokemon's stats and identify what their highest ones are, then build their movesets around that.
For instance, you don't want a Blissey with many attacking moves (especially physical) because her offensive stats are crap. Instead, focus on giving her status moves/supporting moves/healing moves/ etc.
In contrast, you're wasting your time by giving Typhlosion any defensive moves. Typhlosion is a Pokemon that's meant for offense, so focus on damaging moves with it.
Furthermore, identify what side of the physical/special spectrum your Pokemon belongs to.
Chesnaught should not, under any circumstances, be using any special attacks or attempting to tank special hits. Keep it in the physical spectrum. On the other hand, you should never use physical moves on Manectric. Keep it on the special spectrum.
Blaziken is one of the few Pokemon that can use a healthy mix of both.
Defensively, build Blissey to take special hits, but use Skarmory to take physical ones.
Etc, etc, etc.
How do you know which moves to give which Pokemon? Check their stats and play to their strengths.
I'd hate to be the one to tell you this, but without pokemon with proper EV training and decent IVs, you aren't going to get very far in rating battles. If you are really that against making use of EVs or IVs, I would recommend at least giving your team viable movesets that highlight their strong points.
EVs and IVs are extremely important in competitive battlin. EVs are the easiest, every 4 EVs give 1 stat point in said EV, for example 4 HP EVs give 1 health point. There's a max of 510 EVs but only 252 EVs may go to any particular stat, which means you can maximize 2 stats (for example attack and speed in a physical attacker) and raise a single stat point in another stat. EVs are a lot easier this time around thanks to Super Training. You can save, use a reset bag to find out your Pokemon's EVs and soft reset the game to not actually lose them, or simply use the chart on the side to get an estimate. IVs raise stats via a calculation that I don't have memorized, if you're interested in learning it make sure to check them out on Bulbapedia. Long story short, they're important. They're not that hard to get, but they require breeding. I can go further on in detail but I'd need your team's specs. PM me if you'd like further help. :)
Do you watch wifi battles? There are some poketubers that upload ranked battles like shadypenguinn and nbz.
If you want to do good in online battling the only tip one can give is to read up on everything related to competitive battling. Because if you state you're not into EV's and IV's, then that explains a lot why you keep on losing. Pokémon not specifcally trained for competitive battling are going to have a hard time battling against Pokémon that are, even if you use high-leveled 'mons. Not that everyone's into competitive so there should be opponents that are on a more equal level, but most people that you'll come across online are.
So I advise to read up on competitive battling, for instance, start reading up on what EV's are and how to use them. They matter a lot in battles.
And if you're not interested in competitive at all (which would also be understandable) but you also hate to keep losing, I would just advise to look for people who aren't into competitive either (non-competitive friends, just-for-fun battle clubs) and have battles with them.
You won't stand a chance without coverage moves, correct natures, IV and EV training. Battling tips will not do you any good.
I mean you could watch all the bruce lee movies you like and read all the karate technique books but without actually proper training you'd get your ass kicked in a fight.

They will take the useless spoon that is your current team, melt it down and reforge it as a shiny spiky thing to go kill other pokemon.
Describe what happened in your first game please?
Learn about Ivs and Evs then, cause if you want to battle online knowing what they actually do for your Pokemon alone is vital imo. That alone can help anticipate what you should expect from certain Pokemon. Like Garchomp, it's best ivs would usually be attack, and speed so you can anticipate that it'll hit hard and so on.
But really Ivs and Evs aren't all that fancy. Essentially you can think of Ivs as a Pokemon's DNA, they're born with it and grow up with it. For Evs they're like necessary vitamins needed to grow up strong. Combine the two (strong genes, and vitamins) and you have a strong healthy Pokemon. Doctor nonsense aside, you might want to look at your Pokemon team and see if there's any major weaknesses, their held items, or even natures to make sure you have a team that's well rounded for ranked battles at the very least.
Try Super Training
I suggest stopping by the mentorship program run by us at the BBL. We can teach you stratagy, move sets, and breeding. http://bmgf.bulbagarden.net/f518/bbl-mentorship-program-161140/
This isnt really advice but I too am not really interested in EVs or IVs but in online battles you wont get far without em. Quite unfortunate; I wish there was a way people could be able to battle others who dont EV train or IV breed and stuff. Oh well.
I'm in the same boat. With no job, I'm stuck waiting on Christmas and Birthday (hopefully Christmas, as my birthday is roughly a week after all the early game promotion stuff ends). Fortunately for me, though, I already got a 3DS two years ago, so I only need money for the game itself.
Good luck, pal! =]
Yep. I don't mind being called a redneck XD
Um... maybe you? It's not like I'm calling you a redneck or anything...
Or you know, fandoms consist of more than a hive mind and different groups become the vocal minority in different settings >_>
This is fandoms in a nutshell. The majority in the internet community always changes there minds when something new appears.
I think White 2 is the sequel to White and Black 2 is the sequel to Black.
I've done it before. Trick is to take a few breaks so you break up the carpal tunnel.
I like to know trainers' teams in advance, but am staying away from plot/ context spoilers.
