From Reddit: NO level sync when entering a dungeon with less that required players!

They never said they were removing experience from the dungeons. =)

You would not get roulette reward, because premade parties can't start low level roullete (or how lv17-59 levelup dungeon roulette will be called again). What remains is the exp from the enemies. And look how much exp from a lv 17 enemy you get with lv 50 ^^

It will be more for farming gear for glamour or GC seals. Everyone who want exp will still do roulette.

Last i read about it, current lvl50 and 51-59 dungeons will be part of the high lvl roulette, but the option to enter uncapped in smaller groups will be in the DF, so i guess activating it will prevent the use of roulette, or at least this seems to be the more logical way to manage it.

Yes, but you would need to be overleveled and/or overgeared to do a dungeon solo with success.
Also the current lv 50 dungeons get an own roulette, seperated from the lv 51-59 dungeons.

This is incorrect. They have specifically states that lvl50 dungeons will remain in High Level Roulette, while 51-59 dungeons will be added to the Low Level (or leveling) Roulette.
