Smn rotation has always been and will probably always remain the more difficult rotation compared to Blm..

BUT Blm has always been and will probably always remain the more difficult class to use in real endgame content..

Blm "slight" buff of ca. 3-5% and a very slight Smn nerf of 2-3.. or something in that range (imo Smn is doing a tick too much in 5.1 compared to all dps, while Blm is doing a tick too low compared to all)

or just buff Blm 5-7% and buff Rdm 3-5%
