POE2 Atlas skill tree question

So, please correct me if im wrong but in order to put points into, for example, the breach tree... I need to have killed that pinnacle boss? The boss that GGG has said is one of the toughest they've ever designed?

If this is the case, it almost seems kind of backward to me. If I want to do more breaches, and juice up breach, and tailor my atlas and endgame experience toward one or two activities, I would need to have done bland/vanilla versions of that content already? There isnt a way to juice them up otherwise? I want to do more breach but need to kill the 'toughest' boss in all of poe to enhance that breach experience (for more loot, drops reward etc) ???

Otherwise, I assume we get the vanilla experience of these different endgame experiences, correct? Do we have any idea how often and how much control we'll have to juice our maps with specific content that would lead us to these pinnacle bosses?

The idea is that you will be trying to farm that one specific content type more and as a result, beating the "newbie" version of the new Breach boss will allow you to both spec into more breach farm efficiency as well as get to the +4 version, which is the Pinnacle Breach Boss.

In reality though, farming is much harder in this league. I have not encountered any of the pinnacle bosses, I have got 55 breach shards and 7 simulacrum shards and I'm already lv 86.

being able to spec into the farming BEFORE reaching the boss would make reaching that boss much more realistic.
