I don't know about you guys, but I LOVE in leveling roulette when I have to reset my bars as a healer to make sure that my basic attack spell is actually available. Nothing like taking 5 seconds to swap my suddenly useless stone 3 skill to stone 1 for a single dungeon, or making sure that my Malefic 2 spell isn't keybound as my basic attack since that spell is only available in 4 out of 17 leveling dungeons. How about those random fates you stop to help with, only to realize your keys aren't bound for that level, and you have to fiddle with your ability page to find the appropriate attack?

Oh, and who doesn't love having a warrior TP starved in level 15-27 dungeons because you no longer have access to invigorate (marauder only) yet you also don't have access to the 3-hit combo (level 30 and up) that was designed to conserve your TP?

My favorite? Only having access to one cross class skill in Satasha and Tam-tara as a level 30+ job, while you had access to multiple cross class skills when you were there the first time. I had the most lovely satasha run today with 3 newbies who wouldn't tank or deal damage properly, so I was doing all 3 roles as an astro with only cleric stance. I certainly couldn't have used the protect and swiftcast skills at all.
