If you compare it to the days of original!Dark Arts granting increased healing or enmity or causing attacks to inflict Blind, as well as the potential growth into other sources of mitigation and utility -- tools that actually expand our gameplay and ability to react situationally -- our immediate use of MP for almost exclusively damage purposes and to limit TBN remains pretty narrow, even in that scenario.
Right now, you can't really diversify our use of MP without adding buttons that are all basically equal (or only situationally superior) in damage value; any less and you won't use them, no matter what other utility they may provide. Even having them be buttons that consume variable amounts of MP has to be weighed against you spending 3k to activate TBN to get Dark Arts; if it costs more then bursting TBN's barrier becomes a damage imperative, and if it costs less then spending Dark Arts on them becomes an inherent damage loss.
