Edit: After reviewing Spearhead's playing card, I question the integrity of my above post.
See what I mean ?
And let me make it clear that I heavily play 3s and 4s. I really do enjoy them. However, trickle up balance is really the only way the game can be balanced. At the end of the day, 1s and 2s are important competitively, and sometimes amazing 1v1 and 2v2 patches can fuck up team games which is unfortunate. CoH 2 might be in the worst balance era since launch, but its not because it isn't being worked on, its because of how destabilizing the large changes being made are.
Basically, since the weapon profiles patch, the game is enivtably going to have an extremely long road ahead of it for balance, but every patch adds or works towards new mechanics that in the long run will improve coh 2. Think about pathfinders and the new JLI. Its a cool mechanic with the headshot crits, and it turned the JLI into a cheesy high DPS partisan unit, into something that requires more planning (but also gets lol nades). It still isn't perfect, but its working toward an eventual greater state of balance.
