Vaal temple mechanic is the most punishing thing ever

I know you are tired of this kind of feedback but its just extremely frustrating how painfull this temple is

I got to have the temple ready for the first time after 2 weeks, it took hundreds of maps, and i finally got both the access chamber and atziri connected

You go in, click in the chamber, ok lets go for atziri, you get oneshoted by a random rare with a specific combination of bufss and 100% effectivenes, you get out in the first death

the access chamber desestabilices, half the temple desestabilices, and you get back by how much? minimum 18 maps, minimum, more probably 30 or 40 for a new try.
