I enjoyed Dynamis for years, partly because i kept lvling new jobs over the years and always needed/wanted more gear drops from it.

I also really loved lvling up in XI. I just had fun making my character stronger and more versatile for whatever my LS needed. I would even skip LS events when i had found a "good" EXP party. For one thing, it took longer to do and people with many jobs at lvl 75 were valued/respected more than ppl with all jobs at 50 are here on XIV (pre Abyssea, at least). Hell, i never even got every job to 75 (or 80+) on XI, and i played for 6.5 years. EXP parties just felt so much more fulfilling than they do here.

I've had everything 50 for a long time now, but even back in the day before you could aoe the crap out of groups of mobs, before the implementation of chain bonus...EXP parties were just not as fun as they were in XI. I don't see it being any more fun these days either with the implementation of chains, etc. I actually kind of dread leveling Arcanist in 2.0. In XI it seemed like every fight had more strategy involved instead of just mindless killing if that makes any sense.
