Agree with you, what also happened with the removal of Kaiten Samurai went from one of the best Buff feeder class in the entire game to one that doesn't synergize with 1/3 of the raid buffs in it's 2 minute burst.

They should have just kept SAM the way it was and have Shoha turn into Shoha 2 when having 2 Sen Stickers and same thing with Hissatsu: Senei and Hissatsu: Guren
