4th ascendancy trial is ludicrous.

-I have just spent 48 hours trying to do my 4th ascendancy.
-Over 20 chaos entry tokens and over 200 trial rooms attempted.
-Multiple duplicate key pieces inhibiting me from entering the final boss and had to buy the third piece.
-I've had two attempts at the final trial boss and lost both times. This is my bad, and probably a skill issue. I'm a level 90 stampede warrior using hammer of the gods as my single target.

-After 48 hours of doing this I'm giving up, it's the most frustrating experience I've had in 30 years of gaming.
All this effort for the passive node i want which gives me 20% extra damage.

I hate this and I will never do it again. Even if i was successful, I would still be absolutely pissed off having to go through all this with such little reward.


Solution:
Chaos trials would be fine if:
1. You always get the key piece you need.
2. You don't have to get all three key pieces all over again if you fail the final trial master boss.
3. You don't lose exp for failing within these trials.
