No, she is justifying.
i170 is i170.
stats make it easier but in terms of iLevel, the NQ is still getting the same treatment.
Let me give you and example.
I use an HQ main, level 52 tool to craft a level 55 recipe at level 56. I can't get it over 17% Quality (I have tried this)
I use an NQ Main, level 55 tool to craft a level 55 recipe at level 56, I can get it to 100% Quality. (look at the 52 HQ main hand and the 55 NQ - the stats are the same)
I did this with Weaver.
Our character is a mannequin. Everything is tied to gear level now. Stats are important and while it is obvious you want as much as you can get at end game, if you end up in NQ blue, you will still be capable of executing all recipes for the 60 level, even the 3 star we are eventually going to get.
