Spend all talents to apply changes restriction

Hello,

As a player who returns to retail from time to time to check out new stuff, it’s incredibly overwhelming to try to understand how my class works after not touching it for over a year.

Having the restriction where I can’t gradually learn how a certain spec works by just going down the talent tree one talent point at a time is infuriating. Why won’t Blizzard allow to apply the talents partially?

I understand that at some point I have to suck it up and just learn the class. But it can’t be that the best way to do it, is to level a new character.

It would have been much easier for returning players to get used to the overwhelming amount of abilities if I could just gradually fill up my tree on a high level character.

Right now Blizzard expects me to understand the interconnection of a multitude of passives and abilities all at the same time. It’s too much.
