i dont see the big problem in helping lower levels level up,
as i wouldnt even dare have them fighting enemies they could NOT kill by themselves anyways, if barely (HP in the red etc), so i dont have any issues with tanking the majority of hits (i use status modifyer attacks, dirt, curse, taunt, etc, they register just as much as me attacking the enemy so i get a few hits on me as well, while adding a bunch of effects to screw up the enemies aim or resistance etc, while keeping the majority of the rep for a friend, healing as needed), its not like im sending my level 20 friends against a few seabeards anyways.
its the friends who say lets go attack "insert an enemy name 10 levels above their current level" that really need a reality lesson, i can only do so much, if they wanna take a swing..i aint gonna stop em, have fun in jail
