PvP league

What if when creating a character, you could put them into a special PvP league. Instead of there being any PvE, you level up your character by PvP. Every 5 or so levels you would get a new gem, and your characters base gear would change as you level up. You could get currency items so you can buy from the store and enchant items (access to private stash but not account wide, or maybe only for characters in the PvP league.) This would allow the game to have different stats for spells/skills in PvP league as to keep it balanced. As well as allowing the game to be more skill based, by allowing you to change up the skill tree or by setting very similar max healths and manas.

too complicated, but the general idea "you could level by pvp" is bad in this case.
it worked great in warhammer mmo, but here you should be removed from hardcore league when you die. this would not work in pvp.

already in the working its called cut-throat league and has been in the making since CB. you can enter other peoples maps (even at level 1) kill them and they drop they're gear for you to take (30% of theyre gear drops) also if you have exp they lose 30% exp and you gain theyre exp. if you dont believe here is devloper chris playing this league himself. http://www.youtube.com/watch?v=rgb4kRHRLcI

Ears or other body part members as a reward. Everything else has already been discussed on.
