Yep, I know some people feel that way, and that's why we made both the requirements and the gains from leveling up milder than they could have been. A lot of other folks love this sort of thing though, and have actually been bugging us to add something like it to AI War since 2009 (off and on). I always said no, but here we thought it would be fun to do in a limited sense.
But yeah, as with anything, we knew not everyone would agree.
