PvP Battlegrounds Discussion

So I was thinking, wouldn't it be cool to have battlegrounds like in WoW? Like CTF (but with decent maps, no offense), then CTA (Capture the Area), eh what else was in WoW... I can't remember, but you get the idea. Also, the join system could be different, not like people can join and leave anytime, but you go to an NPC and sign up, and after some time waiting in queue, an option would pop up: Join this and that: 1) accept 2) decline and if people left during that BG they'd be penalized? If this was thought out thoroughly, I think it could be pretty cool. So, yeah, discuss. >.>

Sounds pretty good!
Tho I have a thing against the signing up part >.>
Haha, mainly cuz I'm impatient and I want to fight right away.
