I have the same issue, however I think it’s actually okay not to get knowledge reset.
Let’s not all rave in madness at the slightest bit of resistance we get from the game, eventually you can max everything out.
The RPG element of this is pretty cool, my only problem is blizzard half-baking things in order to leave a way to go back in case players don’t like it, which blizzard always does when introducing new systems.
The profession system is really cool, but blizzard should’ve expanded on it way more and made it much more complex and involved.
