hmm as i said before i love this game and most everything about it, if i could ask for one thing it would be a "auto send" option on the waves. I love the in depth-ness of the game, but when you are leveling your heroes, it gets extremely repetitive
so... someone really needs to stop copying /b/ with the whole "Sup Dawg, we heard you like achievements, so we put some badges in your challenges so you can achieve while you achieve."
