Is assaulting Bunkers too hard ?

[wiggum]

For me in game one thing in bunker war (and extensive to urban warfare) could be made arty more capable of be a fatigue dealer... see arty allways dealing fatigue, more in light defenses and less in heavy defenses but allways increasing target fatigue... with this to mortars and even direct fire infantry/antitank guns could be more usefull to in combat.

Great point, i think thats another point the dev's should look into.
Does Arty deal enough fatigue or should this be increased ?

I think we have gone to the core of the problem.
Fatigue !

Direct & Indirect fire should maybe deal more fatigue generally, this will lead to units disrupting and breaking a bit faster.
Maybe assaults, even if failed should deal fatigue damage to the defenders (and attackers of course)...
