Honestly, I see it as being a bit like D&D in style. You're the GM. You created the game. You designed the roles. If you made a mistake or think that something needs to be done during play to cover for one side being horribly outmanned or outgunned, than you reserve the right to do so. Hell, most GM's I see include the statement that they reserve the rights to change or add rules as the need presents itself. In the end, it's a game. It's meant to be fun. If you as the host see there is not a lot of fun to be had or are able to make the game more fun or more enjoyable in the long run, you reserve the right to do so. This does not mean the host can screw with both sides just because. It should be for a reason. But as many of you may remember, I FREQUENTLY inserted my own little comments into my game in the forms of flavor text hints and maniacal laughter. I like to enjoy my games just as much as the players. And I'll be honest, if I could have done anything to make Falconwing 2 a better game I would have. What happened in that game was ridiculous.
