Pre T2A....its the whole chasing the dragon thing. I think everyones favorite is the era they began in. Pre t2a, the majority of users were new to MMO's. Everyone was learning together, exploring, it wasnt about being 7x, or maxxed out.
I've never been into PvP, always been a crafter. Those were the best days. The most risk but also the most reward. Without all the new stuff. end ramble.
