Man...demomen annoy the crap outta me.
Somehow...I always end up on the team that hardly uses demomen...and the opposing team has like HALF demomen. They just spam all day long...it's very hard to get past an area they're defending...
We've been saying there should perhaps be some class limitations after all. Only a certain amount of demomen, etc at once. The problem is...sometimes we like to all rush Scout, or get a lot of Medics and a few Heavies...the option to limit classes should at least be in the server though.
Another thing is the Spy Zappers...they REALLY need to put a limit on them. I suppose that's one of the Spy's big objectives - to take out sentries and dispensers...but sometimes I am FULLY aware that a spy is coming right at me, so while I try to kill him, I'm also trying to repair my crap...and every time I move to my dispenser, he puts another Zapper on my sentry...then another on my dispenser......by the time I kill him, I usually lose one of my structures.
It'd just be more rounded I think if the Spy only had, say, 4 Zappers, and if he couldn't destroy the structures with 4 Zappers, he'd have to retreat to an ammo box. That would seem fair to me...
