I believe people are forgeting what is the MMORPG description and believeing they are playing a MOBA or FPS shooter for competitive purposes (ok for rated arenas).
RPGS are based on progression, rewards, adventures, social. Not street fighter fight stage model, select your character and it comes "done" for you.
For the PVE players saying it is cool cuz they will now try PVP its fine, because if i didnt have to get alot PVE gear for raiding i would also try to learn mechanics and kill bosses.
