Make ascendency trials more compelling with mechanics of a new build previewer and tuner

Right now the trials feel like a current build check based around a mechanic I don't particularly enjoy to get a key character upgrade. If it was instead more of an opportunity to preview and tuning a new build to beat the trial, it would be more valuable to me as a player.

suggestion:
1) start the trial with ascendency points loaned to the player. "Can you handle the power? If you pass the trial, they are yours to keep in the name of *whatever god is behind that trial*"
2) allow the player to freely respec all passives along with the ascendency points at the start of the trial. (it already costs time to respec, I don't understand why this should ever cost gold but...)
3a) Upon passing the trial you get to keep the ascendency points and have one last opportunity to freely tune your passives before they are locked back in
3b) Upon failing, your passives are reset to what they were before the trial. better luck next time
