Even if the game is so broken at this point, I wouldn't have a problem with a server rollback. Guess it's a good thing the playerbase is so low, if we had the subs WoW had, it would only be a small percentage of the population all running around with a bunch of 50s they didn't earn.
i'd be pissed if theres a server roll back, i got almost all my levels solo or in a old school grind party. you know who didnt earn there 50's where there clueless in a party like mages who get aggro then run away, tanks who dont have a at least 1 hate grabber on there action bar, theres some people who wont party unless its a power leveling party.

by the time version 2.0 comes around there are going to be people playing now are going to be selling accounts and we'll still have noobs with all lv50s and they never touched that game before.

SE is just going to be shooting there self in the foot if they dont make some kind of checks & balences in the game. right now its free for all people will just get bored when they can get everything in the first week or two everytime they release content, i remember in FFXI it took ages to get everything and when you finshed something you actually felt good about it.
