On the subject of Turn 3. I could picture a couple ways to make that Turn more rewarding and fun, but, without a drop I doubt anyone would appreciate a turn like that again.
I mean, for example. Have a slow moving ADS spawn near the entrance. Give it an AoE insta kill that doesn't go away until you reach a switch at the bottom. Finally, make each Jump pad locked until a certain number of Mobs are down.
Bang, a literal DPS race. Then Itd all be about getting to the bottom, flipping the switch, then burning down the debuffed ADS.
Not that they'll do this to turn 3. Just saying, work changes like that, that sort of Turn could be fun, if there was a Drop.
