Honestly, asymmetric balance is one of the few things that keeps me hooked to this game. Every faction is so remotely different that every game plays very differently. The only bad aspect, is that even with all this diversity, only a few strats are viable, so in the end, every competitive game looks like any other.
Perhaps I should have added more because that is my point. You can get big differences even when things look somewhat similar, and small changes are easier to make when things have some similarity without breaking other big parts.
So many balance choices don't seem to happen in COH2 because.... DIFFERENCE! So we have very different factions that are only competitive if played in only a few particular ways. And this is better how?
You can still watch good players stream COH1. Wehr and US LOOK really similar, particularly to people new to the game (both have doctrinal MGs, mortars, basic infantry, scout vehicle, snipers, AT guns, HTs, light armored vehicles, AT armor, medium tanks, AI armor, med tents, FHQs, mines, wire and tank traps, etc. etc. etc.) But they play differently, they are very well balanced, and because there isn't lots of cheese to use or defend against there are multiple viable strategies for both. (with the bonus that you could sometimes change your style/strategy in mid game if it was necessary.)
Another game deisgn flaw I think is the VP system. at 500 points with ticks every 3 seconds it is designed more or less around the same length of game as COH1, but the tech to end-game is faster than it was in COH1.
