DA i'm not a big minmaxer when it comes to exalting, at least not in the way a lot of people seem to be. so for me, "most profitable" is whatever gets me the most money in the shortest amount of time. i'm 100% down to do say, 50 7's rather than 50 5's, because i can get way more out of them from a pb or raffle or exalting myself than i can from the 5's. 7's just pay more, even if they take more time and aren't optimal. my big exalter (levels wise, if we're talking pre levels) days are behind me but i once pre leveled 3000-ish levels for a push. another time...i don't remember the levels but i had 300 dragons done and at least another hundred more dormed someplace. i'm definitely not one of the ones that does 4000 levels or more every push though. not unless i get really lucky attending. but that's by choice.
