Brit commanders not OP ? Croc ? Commandos ? Avre ? Nuke arty that destoys entire armies ?
The new OKW commander is definitely stronger than some of the current OKW commanders it might need some tweaking but at least it's not gonna screw over the entire game for several months like it used to be when new commanders were released. If you want relic to release balanced commanders there's always a risk that they're slightly too strong/weak but I would much rather take that risk instead of having a new tiger ace.
All you mentioned are going to be toned down.
Stronger then what? Like all OKW commanders are stronger then this new one. Maybe Special Operation commander is weaker ... well, not weaker but lets say "on pair", and this commander sucks ass. Here is some fast facts why this commander suck:
1) Insanely muni dependent.
2) Volks already have flame nades to deal with garrisoned units. "its not very cost effective" is questionable, because using this new commander force me to use more then 1 sturmpio AND i'm left without ANY elite inf tanks. Not to mention that "its not cost effective" to pick commander just to counter this maxim in building and then play without any useful stuff ... but hay you countered maxim.
3) I have to rely ONLY on obersoldaten later on, since I wont have effective AI inf (and we saw how much time hetzer need to kill someone). So again I have to spend muni even on obersoldaten (who sucks btw)
4) Hetzer comes too late AND cost hell of a lot fuel AND Pop-cap.
5) Brad said that overall stumpios performance with flame is the same as without flame. And they are even weaker with flames against targets out of cover. And if they are weaker\the same then whats the point? Sturmpios are useless AI inf past first 5 mins.
6) Recoup losses ... well, not like OKW is the least MP starved faction, but it also cost you 80 muni.
7) Salvage commander already provide Jaegers, arty which destroying howitzers, AI tank (which is cheaper AND more effective then hetzer) AND gives you tough salvage.
8) HEAT shells got fixed and now they are finally useful AND this commander have Sturmtiger - heavy blob counter.
9) Rocket barrage ... mkay, you could save 100 fuel, have a Hetzer and then spend 200 muni per Stuka zu Fuss barrage, with SAME sound, with FLARES, with SAME damage. Fair trade.
So again how this commander is useful sorry? This commander cover only one area - OMG ENEMY IN BUILDING BURN THEM. But there is 10001 way to deal with them using correct OKW. Its not about UP\OP commanders, its about commanders which simply dont worth picking, since there is hell of a lot other commanders which can be effective in different situations, not on 1 out of 10 games.
