The problems is too glaring, not just 1 class, but all classes are a problem.
#1 Mail, Plate, Cloth, Leather matters none anymore. (Debate me)
#2 Killing Blows are 30% what they were years ago in the PVP system.
#3 Killing Blows are like that because each class has too much survival and healing, even with my undergeared a** returning to the game a week ago, my biggest attack seemingly does nothing to any class, I can imagine what arenas are like.
#4 Too much CC, endless stuns, and the global cool down resets or durations has PVP in a ridiculous mess.
#5 Range has too much power, least some time back a Plate class like Warrior or Pally could run into a horde of enemies and survive for a minute, now they blown up like they got hit by a bomb, most in part of how too bursty range classes are. (anyone know what the class makeup of arenas are at top 10%?)
#6 PVP gear is not scaling up to where it needs to be, PVE players should have advantage to some extent with gear in PVP, but its too much right now, 40 iLVL difference is good game for lesser geared. PVP Gear should be scaled to a decent level where the player can compete in PVE dungeons if they choose to go PVE route for brief time. (concept that worked back in the day also).
#7 Bring back talent trees, make each player and class unique or at least try to, PVP is unfun because every class is using the same 3-4 attacks in rotation and same 3-4 OH! BS! buttons for survival. I also notice (Target needs to be in front of you) is something that has started lacking in many PVP instances as well.
Anyone got something to add?
