Personally i didnt hate wotlk, but i would like to say i enjoyed tbc and vanilla slightly more. But no matter what changes has been done to wow in the later expansions its still wow, and still an amazing game.
And i just had a tought, didn't people use to say the same thing about tbc, that they hated it and so on? and suddenly in wotlk i heard people going nostalgick about it... the only logical thing now is for people to be nostalgic about wotlk and hostile to cata XD
My hope is that in cata the feeling of beeing together with people and playing is brought back. For example, i was on my way to ferelas and i had pvp on after killing a guy 10 lvls lower than me that was walking around thousand needles... ahhh i just knew he was bringing backup when i saw his body not becoming a skeleton :P but i didn't think i would be found in ferelas. I was wrong and as i was killing an ogre i saw this orc warrior riding in the distance i quickly mounted up on my 60% mount and fled hoping the pvp thing was gonna go off soon, he finally caught up with me and charged me, i samm pressed frost trap feign death and jumped till i thought my space key was gonna fall off, and right before i was dead i heard the most wonderful sound... flash of light, for then seeing a paladin riding on his golden horse in his judgement set atacking the orc and totally owning his ass.... ahhh, btw i rerolled paladin a few days later... but thats way off topic for now...
