The bottom line here is not the speed at which you can craft a T6 piece, but the fact that you cannot at all.
In the end you WILL be using T6 for endgame gear, and not ONE piece will be craft able. That throws crafting to the ♥♥♥♥ pile. If you cannot see that, you are deluded.
I don't care if I have a 5% chance to craft a purple per craft attempt with max crafting skill for that item. It should be possible is all I'm saying. You already HAVE to loot for the parts to make most items, why double down vs crafting and make us loot for parts AND get shafted on crafting quality?
