I feel it's mainly the superior indirect fire. Calliopes and land mattresses, mortar pits, USF super mortars, etc seem to decide the majority of my 2v2s. Panzerwerfer is simply laughable .
I usually win the early game, but as the arty pieces like the Calliope and Land Mattress start coming out, I will slowly use my entire force (if the USF mortar or UKF mortar pit hasn't RNG-wiped out my 4-man squads and sniper by then). Rarely does it feel that infantry combat has much significance at all to the outcome of the match, which is sad.
I feel like wehr in 2v2 requires you to be some micro god to somehow constantly move your grens between MG-bursts to avoid getting mortared.
Axis were once known for their good late game. None of that is left now.
This isn't specific to 2vs2 games, but one of the most "wrong" things which also apply for team games in this game is that mortars/isgs and pack howies can be so effective compared to the effort you need to put into using them. The amount of damage/micro tax on your opponent is far too much when compared to the actual effort put in by the player that is using them. The mortar pit takes this to an extreme where you don't even need to retreat, reinforce and reposition anymore. Instead you repair and brace every once in a while.
I couldn't agree more.
It feels like the skill ceiling of this game is now lower than ever. Most of the work is done by auto-fire mortar and 1-click arty. Infantry combat is often decided by whose mortar hits first. This combined with late-game rocket artillery that has the potential to wipe multiple squads in one barrage (even if you don't blob).
