Standing outside the Caverns of Time, ready to go forth and disrupt your past. What would you do if you could do it all over again? Looking back with what you know now about the game compared to what you knew then, would you make the same choices? I started playing during The Burning Crusade but before a lot of the experience cutting from 0 to 60. I started with a druid on a normal realm because, being a newb, I thought "normal" meant you could get away with doing a little bit of everything, PVP or RP, whenever the mood struck.
Boy, was I wrong.
Personally, then, I would keep my character choices as they were (yay, druids!), but I would roll on a different server type (changing from normal to RP). Why not just reroll or pay to move now to a RP server? Because I'd have to spend $250 to move my entire crafter's network or cave in and finally rely on the AH with only one toon -- and then I'd miss my gadget-wielding maniac warlock gnome, and the rest of my army of alts would sit abandoned, collecting dust. Lonely. Not to mention the friends and family I'd leave behind.
What about your faction of choice? Horde vs. Alliance was a practical choice for me, since that's where my friend was who introduced me to the game.
So if you had that giant reset button and could slap your past self on the back of the head before doing something you regretted, what would you do? Or would you do nothing?
