When I brought up the other stats, I was moreso trying to demonstrate how little luck actually affects things in comparison, not really trying to talk about stats vs each other in general. GUI is the strongest basic attack main stat yes, but it's pretty worthless for a non-basic attacker who won't benefit much from it outside flank hit/slots, and I'd take WIL or STR over it any day in that case. Evade, glance, and evasion ignore is another topic as well, but not one I'll cover here. 

The two reasons I want to avoid giving more crit to Luck is one, people had concerns about devaluing crit eva in the last thread which I can see to a degree, and two, it wouldn't solve the issue of making luck on non-crit builds feel terrible. Let's say I want to use a lightning custome with its 70 will/40 luck scaling, and I'm not using lightning crits. What is luck really providing me in this context outside elemental attack and a marginal amount of crit eva that will probably not matter? Yes...  I Could just use another tome alongside luminary, but it seems pretty silly to have no real reason at all to use luck-scaling weapons outside basic attackers.

Trickery style effects on attacks for luck could be interesting, though I'm not really sure what skills you'd tie that to, and there's fact that if you're not using those skills, that Luck buff does nothing for you.
