trial spawner vs vault rework

so when preview 1.21.0.20 dropped i went on tested out hardcore and i found 2 issues:

1. there are more trial spawners than in java the spawners weren't balenced at all 1. when i went in spectator to go down to the structure i noticed i had been extremely unlucky and got the bogged for ranged mob i went in with iron armour died went in again with only a sword and food died again then went back in and died due to the spawning of natural mobs bug i know that is planned but my conclusion behind the death was not being able to regen fast enough so unless this is a parity change happening in 1.21 then this needs to be changed because if i was to not be able to spam click (which is the theory i've heard behind it) i would proberbly have survived or at least for a little bit longer 
2. so after that chaos i moved on to the next room which was the powdered snow room and 8 had 3 spawners 1 was bogged 2 was bogged!!! and three was BOGGED again i think this needs to be more baleced in that you only get one of each type (ranged melee small melee and breeze) forgot to take screenshots of this room i'll post it in comments eventually the
3. note: i was doing the ominous trials
4. note: i couldn't find a preveiw category so i just went here
5. note i can upload a video to if you really need more evidence this isn't just a story
