Re: "1/2 as effective against X" Limitation and Player Controlled Allies
 

The other advantage of using Meta-Traits instead of modifiers on attacks is that you can then consider non-IA damage sources to be typed. Thus, if your grass pokemon gets burnt in a mundane bonfire, you can consider it weak to it without worrying about whether you're jipping it. Note that you don't neccesarily have to do this. It's up to you as GM whether non-pokemon damage counts as typed, but this system allows it.
