At this Point, I want them to bring back the Idea of Kaiten..
if we can't have Kaiten back, then give other skills the aspect of Kaiten.. or something in that direction, My Idea if they don't bring Kaiten back: Reduce the Kenki Cost of Shinten and Kyuten to 20 Kenki and give them a Buff (either Potency Buff or Direct Hit Guarantee) for the Following Attack, suddenly we have turned Kaiten into an Attack basicly. Yes, the fancy Animation would still be gone but there are Videos (on Youtube) that showcase the Skill in its glory but the Idea or Aspect should be preserved!
I'm just sick of sitting on 20 Kenki with nothing to do with, even though we never had that Problem in the first place! .. if they really decide to kill off the Synergic Aspect of Samurai's Mechanic and Resource.. then at least reduce the Kenki Cost of Shinten and Kyuten to 20.. would worsen the Shinten Spam? Yes, but at least I don't have to sit on 20 Kenki anymore! Even if I prefer Samurai with Kenki Iaijutsu Synergy and Cone Tenka Goken (same way how I prefer Cone Overpower) the Removal of the 20 Kenki Spender is what stings the most about 6.1 Samurai...
