Realm Vs Realm, you have the rights to DAoC and WH use it.
CC break should have a short cc immunity to it after it is used, i do mean short
Objective World PvP ....oh wait RvR. give us a better reward for heading out to said areas, such as merc commendations based off Valor rank, credits, and rare Open world PvP armor drops/tokens.
Make Outlaw's den and Ilum worth heading to...because id love to kill my own faction sometimes and you are removing Ilum dailies/weeklies
Did i mention that Bioware/EA controls Warhammer and Dark Age of Camelot. The two games with the most successful open world PvP in MMO history. Please use this to your advantage.
PvP alternate advancement. This legacy stuff seems very PvE oriented.
Dont raise expertise too high, there should be a cap to what can be absorbed, and locks players into a set of gear which is supposedly "the best for PvP" there should be variety much like in DAoC where people could make templates.
keep doing what you're doing with the class balancing.
YES, IT IS MY OPINION THAT DAoC WAS PROBABLY THE BEST PVP BASED GAME... THE SECOND BEING SHADOWBANE....BUT THAT GAME HAD A HORRIBLE UI.
