Its somewhat annoying that if you've already completed the main objective of a Challenge, and you die afterwards while pursuing additional points, you still need to wait until time runs out to collect the mats you've already earned. If you release, you wipe the Challenge entirely and get nothing.
Change it so that, on Release (or Recall/Teleport), it performs the "point check" it normally does when the quest completes, so that you can collect your earnings early if you so desired, rather than just stare at your soulstone for 5 minutes (as I'm doing now...)
Would this allow for quicker farming of some quests? Sure, maybe - but you're almost always going to get better mats per minute if you keep grinding out the whole time for bonus points, so I don't think its going to open any exploitative loopholes.
