I personally don't care whether XIV succeeds or fails. XI, I'd like to stick around so I can log into my old character once in awhile if I miss her. My memories with Lux are all tied to a game that doesn't exist anymore... a character model that also doesn't exist anymore...
Preludes has some points about the game - I mean, several of my friends started from scratch and are already 50 and getting higher tier gear - that does seem a bit quick. I agree that the multiple jobs on one char thing will help (as will the "all used up" quests) to slow people down from total burnout - but only time will tell.
I think I am just old and crochety and like the antiquated battle mechanics of FFXI. That's fine, except that I hate the current state of the game. At least back in Voidwatch time I could chill out a bit, wait for a shout and do something that had the potential to net me gear progress. With the lack of population and the fact that it is mostly LS and statics filling up most events now (basically most of the game has become like legion was - with only one or two slots for super specific jobs in any given run) - there is nothing for someone like me to do in the game.
I just read up on the dungeons in XIV and it sounds stressful, not fun. I will give it a shot at some point and maybe I will be pleasantly surprised - we will see.
I think if I had joined the XIV server my closer friends had joined I would feel differently - cause any game is more fun when you're playing with people you actually feel connected to - but really, I am glad I didn't. Been enjoying a bit of single player game action and not feeling fussed to play an MMO is nice.
