Just want to tack on with what Lelila38 said with the whole blm has to learn fights. I found lakshmi ex to be more easy of the two primals to learn positioning on and do well with blm. As for regular omega i learned the fights on rdm before switching to blm for them (can't speak for savage though). That said blm is very rewarding to play with its potential for big numbers (I'm looking at you 32k fouls) and I've even kept up with a few sam friends.
