Plz no timers on exotic quests, the dungeon secret puzzle ones are fine because those are more of an event but the Vox timer is very punishing for solo play
If they're going to have a timer, make it like the encroaching darkness in legend/master lost sectors. Instead of auto-failing, just make it so you don't rez anymore after a time limit passes.
Solos and players who prefer to play slower and safer or who want to explore can finish the quest at their own pace, but there's still pressure to not die after a certain amount of time. Why does Bungie care if you want to spend all day dodging cursed thrall to gawk at the architecture?
