Dunno about you, but in ShB, my DPS aoe rotation as a monk was 3 skills till I ran out of TP. That was it. Maybe do my chakra skill once it hits 5 stacks or pop an ogcd cd, but it was a spam fest with the fun limitation of running out of TP eventually.

Dungeons dont feel all that different regarding trash monsters, sure. But atleast I dont have the TP problem anymore. So its an improvement in my eyes.

If they want to make dungeons interesting, then they need to change how trash mobs operate. Give them auras that require CC (like using repose to actually sleep monsters, but change it so unless you deal more than a % of the monsters health while slept it wont wake, rather than any damage.) or monsters that get stronger the more allied monsters are nearby. Monsters that have an enrage that requires you to single target focus them down first before swapping into aoe rotations. A single target monster that rapidly spawns tons of minions (although each minion is weak) so you use aoe to burn otu minions then go to single target, then swap back to burning minions. Etc. Getting more clever with trash monster design would be the fix. Because as long as you can round up a ton of monsters and burn em down, the go-to strategy will be to do just that. You have to introduce deterrents where rounding them up in such a fashion = death.
