I'd like several things to happen next expansion:
  • Shorter dungeons. 2 bosses or the same 3 but without trash mobs, ideally no longer than 15 minutes to clear. Also no more reused loot.
  • Moving away from using tomes for gear. I would like to see tomes used only for upgrade items while loot is obtained elsewhere.
  • Re-hauling old and abandoned content. Coil, Alex, and soon Omega will die when 5.0 hit. A simple scale up of the savage fights with enhanced gear models is enough.
  • New ways to obtain tome gear or alternative gear types. Such as spawn-able NM fights, trials. Also crafted items you can upgrade with tomes would work.
  • A more engaging relic quest. 2.0 relic challenged you to beat all the primals and 2 unique battles. Lets do that instead of a pointless grind. Relic should be a reward, not pity loot.

Obviously there's common sense things like more items per patch and new not-baby-tier stats.
