Idea for skill tree

It would be cool to have 2 passive skill trees just like we have several atlas skill trees. It would make us want to try other builds all while we can have our
"safe" tree in backup in case something goes wrong. Also they could be used for different content, ex: tree 1 is for bossing and tree 2 is for mapping and clear speed.

What do you think about this?

Also it needs to be check if its too OP but maybe you could make a lab and switch ascendancy and take your other tree so you dont have to create a whole new character, it fixes problem that people dont like leveling new characters all the time.
