Is it possible to make the auto-use on fairy persist through death? Most of us have it hotkeyed by now, but it would be a nice QoL change to where you don't have to hit the hotkey(and potentially goof it) after death.

This would be nice but I can also understand why. If you're dying a lot then perhaps you shouldn't be at that spot. On a side note, it seems like fairy and alchemy stone repop delay has crawled its way back into the game. They made that tweak to make repop faster but I've been finding myself get randomly CCed in Zephyros due to villa buff scroll not popping immediately when it runs out and same with Vell not getting repopped but sitting there with 0 time remaining. It is infuriating as I either have to V or if the CC happens while its on CD or I have a large group on me I can get basically one shot

PvP exists.  Being alive for 5 minutes in PvP is a long time, but you still want to have your fairy turned on.
