I messed up with RAF and my main account with my 90 and other high level alts are not connected to any of my RAF accounts.

however I did set up the chain correctly a > b > c > D > e > f

Bad news is now none of the raf accounts have high level toons. my question is if I take 4 of my raf'd accounts and group with my 90 to run an instance will they still get the bonus xp ? Or do all the accounts need to be RAF'd to make that work?

My next question is what is the best way to boost levels using my set up? Should i Just level the 5 together normally and save all my boosted levels for my next team?
