You were around during the NA release in October 2003? I'm not saying the past is better than the present and I frankly don't give a fig leaf about going back.
**But** back in the days where you had a fixed party of the same six players leveling together (because everyone had to be the same level) the party format was typically: PLD, WHM, BLM, BRD/RDM, DD, DD.
The only people that had to worry about the Skill Chain rotation were the two DD. If one of the two DD couldn't get his shit together so that both were building TP at the same rate then you kicked his ass to the curb and found someone that didn't suck.
Once WoW came along and every game company in the world wanted to dumb down their shit to the zerg mentality so that they could have an MMO with ten million subscribers, then everything changed.
I never had to sit in Jeuno for six hours with my party flag up waiting for a group. Because I was awesome.
But I quit right before COP launched to go play WoW and farm purplez six nights a week in the same lame ass raid zone. Wheeeee!!!!!
Would I like FFXI to return to the much more difficult days of the past?
Let me try Abyssea for six months and I'll get back to you. I still haven't seen those areas.
