Personally, I felt that PvP gears could be a turn around for crafters but it doesn't seem to be the case.

If SE had made all PvP gears, (i55, i70 and i90) obtainable through crafting, then I think it would have made the crafting scene more lively again.

i55 gears could be made through current mats, then players wear them and get into PvP, earn wolfmarks where these wolfmarks can buy new crafting mats specifically used to craft i70 and i90 gears.
