Thinking of playing again

[Striiker]

I'd suggest playing your warrior if you like melee. Warriors are always great to have. I think you went about it correctly by leveling up a class capable of farming to get your warrior geared up. You should be able to find groups in the usual places as you level up. I see people constantly in places like Oasis, Unrest, Mistmoore, SolB, etc... Some times you need to take the initiative and get a group going, other times, you can luck out and get an invite when LFG is up.
The guild scene I think has settled down a lot. Yes, there are still some issues but generally I find that the guilds are pretty decent towards each other and it continues to improve. I'd say get into a casual guild to get some raiding time in and then play your alt when you wish to. It's great to be able to experience both aspects of the game. It's all about having fun.
