a few question !

So after seeing all the changes in kmst and hearin bout the "potential system" from what I can gather -less classes are dead. and atm my new main ( dit ) is 46, he's dexless and I want to plan ahead so I don't have to use resets and can just level him now to even out his build. what ap build would be the best?

what points should I start pumping (str/dex) and how much ? as for funds I have something like 2b if that even factors in or not I don't know.

Also, is there a way to get a char from 30-50 in a few hours?
