Things that come to mind -
- Wehr veterancy like you said (doesn't actually promote unit conservation)
- Wehr Defensive Med Bunker spam (I don't like static defenses or unit recyclers, tbh - the game would be fine without both)
- Allied War Machine
- Airborne Supply Drops (results in strafe spam)
- Off Map Combat Group (not OP, but the most uninspired ability in the game)
- The M3 and Sd.Kfz 251 halftracks need tweaking (right now nobody uses them with just the MGs, unless piospamming vs. Brits)
- Wehr Officer (nobody in the entire history of CoH has ever had a reason to buy this dude)
Not saying that these things are OP/UP or break the game, I just don't think they're very good ideas. The game would be better, in my opinion, if they were removed, tweaked, or replaced.
Anyways, looking forward to the new build.
Wehr veterancy differentiates them from the US and isn't that strong. Some lvls gives minor bonuses while other lvls (lvl 2 Inf vet) gives Elite armor. I can assure you that you need to keep your troops alive. Should they die, you have to reinforce which drain your manpower preventing you from getting veterancy, buildings and new squads.
It doesn't work to spam medbunkers. They cost too much to spam, the medics are vulnerable and you need to defend them instead of being out capping or harassing. It also cements the Wehrmachts design of being a defensive faction until T3.
Allied Win Machine is definetly powerful. One of the things that's hard to deal with. It throws away veterancy however and costs 200 munis.
Strafe can be strong, but atleast there's no goddamn artillery.
No opinion on the rest.
