In endgame, crafting is basically good for three things:
1. Making money.
2. Accessories with vitality melded. Normal accessories for non-tank classes give you 0 vitality, so vitality melded accessories are legitimately better than higher level normal accessories. All other crafted gear is inferior to higher level regular gear which is also more easily obtainable.
3. Helping people much further behind you with gear. Pre-50, HQ equipment is very nice to have (although unnecessary). For a fresh 50, i90 gear is a great way to kick start them into endgame, but they will quickly acquire better gear if they are doing up to date content.
