I know i will be and many many(won't generalize with a figure) others. We read so much about the accomplishments of Raiding guilds sometimes people feel they have done it all. It all depends eh?

1. Been playing WoW since 04', had a bad case of making alts and experimenting with the Alliance on a PvP server. RL friends join WoW, and the majority think PvP and Alliance are "time wasting" and dull in that order. BC expansion drops now its explore and learn up to 70. I break again 3 months or so, only to return and see PvP realm guildies are no longer playing and guild is falling apart due to internal conflict. Oh well, now my mage is gankable whilst trying to finish up menial quests in Nagrand.

2. RL friend who doesn't live near and we don't commune much only by internet convinces me and others to leave Alliance and PvP and lets "do this before WotLk" comes out. I left out much info to keep this as short as i could but basically Re-rolled a horde toon on a new server, for a whole new learning curve(FPs, zones, quests), since i only played Alliance since the release.

3. Here i am at 80 going strong, still havent done Naxx, etc.
IMHO PuGs aren't like they used to be...I tend see more cocky, Less helpful players etc who EXPECT people to know everything prior to running instances. So i tend to end up working with friendly people you meet along the way or guildys. Plus my gear is not ready, need more heroics...

Phew! Srry for so much, just giving a description of how things "can" be.

Now If i would have played WoW religiously up until now? Who knows i might even go as far as to say i am bored of it, which i dread since i really enjoy the game. Its the reason i take breaks, to keep it fresh and current.
