I think buffing the GA is fine but I don't think we need a lot more combat bonuses in the tree. I think the bonuses are pretty good as is.
ElliotS touched on it early on, but Industry is strong because it provides "the economy of war", which is very powerful at this point in the game. Imperalism should do the same, but in different ways. I like the notion of war weariness adjustment or the reduction of unit maintenance overall. The tree already provides great science bonuses for "going war" through the various barrack type buildings...which is another good one.
I honestly don't think the tree needs a complete rehaul, a few key tweaks and it can be competitive.
