Honestly, if they want to help their friends level up, it’s way faster to just tell them to chain mobs 2-3 levels higher than them & use the weekly challenge log, while the helper prep the appropriate NMs until their friend is at least 8 levels below theirs in respective zones. At that point the helper can now kill anything 5-6 levels above their friend to power level their friend at stupidly fast rate in same party.
Alternatively, prep the right NM so the helper can round up & whittle random mobs around the spawned NM down to almost dead, THEN use the NM lv sync to bring their lv in appropriate range so their friend can receive the experience from the kills. But this requires a bit of luck because folks in instance typically don’t want to keep an NM alive for too long.
