Re: YES popcap has made a truly balanced game!
I think they did a good job at balancing the game, but there are some stuff that can be improved in my opinion in order for all the characters to be balanced. Hockey star for example is one of if not the weakest All star variant, which could be easily tuned by adding poison to his weapon considering his weapon already has the poison looking aura coming out of the weapon. Even with that change it would still be under used but will become better then he is now.
There is character on both sides that need a little help but that's another topic.
