Well atm I'm playing WoW. But a thing about WoW is that i find the community a lil'bit immature and retarded. So should I switch too WaR if i want a better community?

The communities are roughly the same, unfortunately.

One is slightly smaller than the other. Mythic didn't carry any super cool community from DAOC over though.

Depends on the server. I know many good people on one WoW server, and a bunch of morons on another. It's all relative.

There are idiots and assholes to be found in every corner of the gaming world, unfortunately WaR and WoW are neither exceptions. It's really all a matter of luck.

I've found that, if you're into actual RP, the RP servers are far, far and away better on Warhammer Online than World of Warcraft - they players are more helpful, the RP is FAR better, and the general tone is more conductive to play and have fun in. I've really only been in a small number of servers on each, though, so I might have been lucky :)

i tried warhammer briefly and i thought the community was better, a lot of helpful people, in wow you get flamed a lot.
