prime example of needing level caps is totorak lv25 and you can spam it for GC seals, and make 3 runs a hour for 3K+ GC seals. level caps also make lower level equip re-useable so you dont have to toss out all the no tradable stuff after you get something better. all loot can be valuable in the lower dungeons also and that can help the noobs complete content because people will do it even after they finshed there quest.

totorak has its loot rewards and secondary loot being GC seal if all dungeons follow that foot print we can always have stuff to do.

In my humble opinion, 2.0 NEEDS a level sync option.
no it dont the game is easy to level solo if you have too in a party you can have 10 level difference, and im pretty sure 2.0 will be just as easy if not easier.

Capped content is fucking awful. Why not ask for content that scales instead?
uncapped is worse, capped is scaling content not everything has to scale up into infinity.
