Indeed. Y'all remember when our gauges actually did something? Sure would be nice to have those back.

The way they've handled new skills in ShB and EW proves we could have everything SAM had without losing space. Just clean up how certain skills are available and we'll have about 4 or 5 empty spaces.

I'll keep suggesting it every thread I can.
Third Eye - Open Eyes
• make Third Eye transform to Merciful Eyes (would be cool if it healed about the same as Second Wind)
• make Shinten transform to Seigan

Ikishoten - Hissatsu/Ogi
• make Ikishoten transform to Ogi/Kaeshi Namikiri
• make Shinten/Kyuten transform into Senei/Guren
(Conversely, they could change the way Meditation and Kenki work and link them together in some way to make Shinten/Kyuten become Shoha 1 and 2 respectively)

So many ways they could alter the existing kit to make room for expansions.

While I'm not happy Kaiten is gone, I would be willing to let it go if something was put in its place for the removal. But as it stands, with nothing to change, we are left with 'press Shinten if available' and that isn't very fun.
