well a player can be returned after 2 years and still be considered returner but he / she is basically a sprout.that's why they added that status i think because most of the returned players i have seen play mediocore to bad, mostly because they don't know how to play or forgot.mentors has no obligation to help a player with any kind of newcomer status. It is there to help people with basics.That's why you need 1 tank, 1 healer, 1 dps for example. You only need to know tanking basics, healing basics, and how to prioritize your dps. Like how to pull enemies, using cds and keeping aggro as tanks, like not applying regen as healer before pulls and how to react as a healer, like when to apply dots or debuffs or how to use combos efficiently as dps. No one expects to give a lv60 ninja rotation guide from a mentor. But if that ninja doesn't know how to use his job properly and if you are a ninja as mentor, ofc you can help. But you have no obligation, that comes from almighty crown :3
