Atlas passive tree

The current atlas passive tree feels off and the progression seems backwards. We progress and getting stronger via maps in order to fight the end game bosses, at the moment the passive points to buff mechanics that we want to play are locked behind bosses. Bosses should give extra points that we can use on the passive tree like poe1(and their points to be extra on top of the current Nexus one).

Also at the moment the 2 trees are separated which also feels off and you cant have all the passives points from the boss tree.

Would be great to have a quest version of each boss, like searing exarch/eater of worlds drop as green item(same as trails of Sekhemas and chaos) so players are familiar with the boss when they want to fight him for real. Now you need to have fragments and if you are not ready for it they will wasted.

Thank you for your time.
