The game is not an unbalanced mess.
Such overblown ridiculous proclamations wont achieve anything except make your comments ridiculous.
Some abilities now cost too little for big benefits they can do, like scoundrel backlash, but there is no need for any general doubling of APs, cost of otherwise.
The current system needs to be tweaked some more, thats all. Not scraped or entirely changed.
I think five base APs would be good, with some abilities that are now 1 point costing two.
Thats the kind of fine balancing the system needs. Not complete overhauls.
But none of that will change the effects armor system has on the gameplay, which is surprisingly good despite it. Not because of it.
It could be better.
