I mean it goes both ways, for people who qualify as SMN and SCH and have a good understanding as both it would be bad if it wouldn't count. But people who just level ARC to 60 to get the requirement done to become a mentor and brag about it and don't have a good understanding and experience as either Healer or DPS and not qualify as a mentor it kind defeats the purpose of these requirement if you can just skip one role.
So what would be best to do?
