There is a huge difference.
OKW scavenger arty actually wins the game in 1 click vs USF. Literally, it wins the game via annihilation. The clumped USF base will fall to the self-repeating arty.
Tell me how that is in any way the same as USF arty that doesn't even kill 1 building per use?
Yeah, i probably jumped on you a bit too early. Nevermind what i said, still i think the easy one click truck nuke should be gone, as i also admitted the scavenger doctrine artillery is ridiculously OP right now, and needs to be looked by the balance team.
Punishing a forward medi truck is a huge hit to the Oberkommando player, especially if it comes at no cost (or risk), or a very low one. If trucks could be called in when needed, it would be okay, but the 3 minutes timer is everything.
Being able to "spread" the base is a feature for the OKW, but if as you suggest, blatant OPness of some abilities push the players to just settle for the starting area, then something is flawed. A whole faction design, or counters are too strong. As i said in the Scavenger artillery topic, i'm all in for a targeted "artillery resistance" that would apply only to USF and Oberkommando base structures. Would probably solve most of the issues. USF can't decide their base setup and positionning, and OKW somehow rely on this mobility to be able to compete with the other factions, that sounds fair to not punish everyone with one win buttons, don't you think ?
