Lets be honest here, there are no "bonus" stats when it comes to the player base expectations n mmos. You can complicate it as much as you want but it's going to come down to, people who want best only, and people who dont care and just look for acceptable. Basically skilling up you are just asking to add the idea behind the current relic system to smaller increments to everything, with a few extra things to worry about thrown in. Given the game is intended to be casual geared in its core concept I vote no.
