I'll agree on Shoha being a joke. The one upside is that I'm not missing a vital skill from 76-80.
Tsubamegaeshi is only clunky to use insofar as we can't use GCDs in between the iaijutsu and the repeat, changing things so we have a window of opportunity to use Tsubame (and thus are able to stagger it) is something I can get behind, making it instant-cast not so much.
Iaijutsu is the SAM hallmark feature and just because we now use it twice back to back it hardly makes us a "melee caster".
