Well, I suppose the argument is that it now significantly outranges Axis indirects (Those that are nondoctrinal, and are an actual threat to it, I mean), and can sit well out of the reach of PAKs and place itself somewhere it is far less able to be dove by tanks, meaning that a VERY deep Mortar Pit is almost like a nondoctrinal howitzer with much better survivability.
I haven't tested the unit myself, nor played against it yet, but I can see how it might be an issue. I think we'll have to see how it all plays out in practice (in teamgames specifically) before any knee-jerk further changes are made. I just hope it doesnt feel too AIDS to play against... though I always go Overwatch against brits anyway, so i can just LEFH it to death if its' too much a problem.
I tried emplacements several times with the new patch. They're still not very good. Most OST will get a MHT and OKW will go Feuerstorm, both of which take down the emplacements quickly even if fortified. The long range barrage has too much scatter and too long of a cooldown to be anything besides situational. It's good for getting the last hit in on a schwerer after you've dropped supremacy or something like that.
I would say that the buffed Centaur feels too good, but it doesn't feel that different from the Ostwind, and neither of those seem to have the impact that a werfer has.
I do miss the dive bomb from Jaeger Armor already, particularly when playing randoms. The strafe isn't too bad, always amusing when people don't watch their stuff after a recon. It kills light vehicles quite well.
