i just like artillery personally...normally it's my "omg he's got too much support stuff and i cant' break thru" weapon. If like say, my opponent never brings out a mortar, or doesn't spam hmgs, you'll prolly nevr see my howie or hummel but since there are points where you need artillery to break thru at times, i use it.
Every side needs some form of artillery, be it light, medium or heavy.
that is like "oh i don't know what to do because there is a hmg (never heared about flanking, sniping, mortar, infantry supported tank attack...)
we can always create scenarios like...what is when there is this and that and this....
artillery need tactical usage and that can be countered easily when not supported
i don't say remove artillery...but i say lower its impact to gameplay to a more tactical role in big pushes and breakthrough and not like "hey i'm to lazy to think or micro, lets get the arty out"
it's not a noob weapon.
in its current state some arty is a noob weapon like
"eh i actually need to push and attack but i don't want so arty them as long as they do the attack move"
I'm sure you use mortars dick, or nebels or stuaks right?
i call mortars support and not "artillery"
and i'm also for a cooldown increase of nebels and stukka ontop of the changes of the other forms of artillery
