Oh, really? You kind of made it seem like you were talking about Defog, not Fog.You pretty much just explained what I said in a much more detailed way, but it's probably how I worded my sentence. I apologize if it was confusing XPNot quite. Flash was a move that lowered accuracy that made it easier to see in dark caves in the overworld. Defog lowers evasion as a move (among other things) in battle and clears fog in the overworld.It is annoying, but Flash basically did the same thing lowered accuracy. Then again it only lowered one pokemon's accuracy.No, you're not understanding. I don't want to see Defog back because I don't think fog should come back at all. Adding an obstacle that nerfs your team's accuracy in every single battle on the route is one of the dumbest additions to the Pokemon series ever.
Fog, the overworld/in battle weather condition is what lowers accuracy during the entire battle if not cleared. It is annoying for basically dragging battles on due to making your moves miss too much as well as serving almost no benefit in battle.
