QoL and reducing number of the buttons suggestion

[CaptainLagbeard]

. Shoha 1 + Shoha 2
. Guren + Senei
. Shinten + Kyuten ( if you must )

The only way to combine those would be if you just gave the AoE version the potency of the single target version... Which for most bosses wouldn't matter but if there was ever any fight where you had adds or even a second boss, they'd become rather powerful.

The biggest thing for pruning extra buttons is more that you have skills that require a different skill or a buff from a different attack to use... Like for SAM, you can't use Tsubame without Iaijutsu, or Namikiri without Ikosihoten.
