So come cata what do you plan to do ?
Personally i find leveling to be the "best" part of wow behind 10 man raiding (i like the sense of community [is that the word im looking for...] in a 10 man raid). I've already leveled all but a rogue, mage and priest to 80 (66 rogue, 44 mage and 50 priest, no real intrest in leveling any of them due to not really liking the classes), and despite having 2 characters in 10/25 man raiding guilds (not really casual, but not really hardcore either) i plan to "dump" both to level a goblin/worgen lock/hunter (havent decided what combination yet....prolly wont till i see animations / how they each look in mail/cloth). Im also undecided as to whether i should a) level "fresh" no "help" from main b) level with boa or c) level with boa +every upgrade available in AH/crafting with mana/hp/stat pots +maxxed out prof (all bought pre release )
