tbh i'm looking forward to noobing out when SW:TOR rolls around, it's what made wow fun to begin with, the sense of discovery and actually learning how to play the game rather than being told THIS is how you play the game, if you dont play it exactly like that, you suck
theorycrafting certainly has it's place, but i think it's a perfectly legitimate concern to have that theorycrafting may completely take over the actual fun aspect of playing the game, as a lot of people simply don't realise that in a min/max situation the best theorycrafted spec and talents are focused around the best gear and a perfect playstyle, whereas 90% of the playerbase wont have either.
wow is in a constant state of debate over what the theorycrafters say is best and what the developers say should be balanced across all specs - the problem is that the wannabe super hardcore players blow the results from theorycrafting way out of proportion and it ends up turning into world of simcraft, i dont want to see such things happen in SW:TOR, we just need to have faith that bioware are better at balancing talents, specs and builds, so it purely depends on the skill and playstyle of the player and that no one spec is better than another in any given class, unless you're honestly clueless at speccing or understanding your class role, cos reading talents is hard.
