i picked the wrong month to quit

so i had to take a month off playing WoW because i couldn't pay the subscription fee.  just started up again today, and holly hell they made a lot of changes to hunters.  apparently i no longer have mana, i have focus.  what am i, a fucking rogue?*  this totally messes up a lot of things i have in my bank now.  also the arrows i used to make and could sell for a decent amount of gold are now worthless.  i had to redo both of my talent trees, which means i have to redo both sets of hotkeys.  i hate this.  i feel like such a n00b when i have to redo everything.  errrrrrrrrrrrrrrrrrr. and i get to so it all over again with my death knight.  i should have know better than to take a month off with a new expansion coming soon.  guess i know what i'll be doing the rest of the day now.  if i wasn't so close to loremaster i might consider rerolling.   /end rant

*i know rogues have energy, not focus, but whatever.  rogues suck anyway.
