It's a bug or unknown feature for me: i did lvlup one of my mentee from 79 to 86 (solo hekaton ftw) and didn't get any mentee marks for that lvl range.. it's normal or as i said before, unknown feature? or just a bug for that char? this char already have pet shots bugged. all the time i need on/off auto pet shots..
you can close.. support said it's "not a bug" if you manage to skip lv 85 and reach 86. so friendly advice, don't use maphr on hekaton/shadith/gwindor/lian and your lvl is ~80.
