I felt people at the beginning of Cata were actually more understanding than any other time.
Am I seriously the only one in here that thinks the majority of the playerbase is nice?
Do you happen to heal on any other class? Because at the start of cata paladins really had the advantage with holy light giving holy power with Tower of Radiance(which got nerfed). There are plenty of horror stories of groups kicking pretty much every other class saying they couldn't heal before the dungeon even started (especially priests).
