Bad Omen Levels in the Trial Chambers

Higher Levels of Bad Omen already makes raids harder, so I think there is a missed opportunity to make the trial chambers challenging to people at all stages of the game. 

Specifics: Higher bad omen levels cause more and stronger mobs to spawn in the trial chambers. Bad omen 5 would be need a fair bit of skill to beat, even with max gear. Rewards should also scale.
