Raf dungeon leveling with 5 accounts. Outleveling their gear :( advice?

I'm trying to level 5 accounts as fast as humanly possible but I can't seem to find a working method that includes raf and honorbuddy,

I've tried using symbiotic but it doesn't work.

They level way too fast in dungeons and by the time they reach level 55 they die to just about everything.

I can't even get past the first pull of ramparts right now. (only 2 mobs)



Any advice? I keep hearing how people level in 24 hours and all that and I cant figure out how.
