I gotta say, i really like the idea of senei/guren replacing shinten/kyuten on ikishoten. Reduces button bloat while still keeping that whole bit working as is and doesn't obstruct anything in terms of rotation. We already get Ikishoten before those two bigger skill so it wouldn't require much in restructuring in terms of when we get the skills. Also, I vote for that Shoha change too since that is the most natural change they could've done when they introduced shoha 2. Still boggles the mind on why it's a separate button.

Also, i hope they don't keep sam at this state. Hope they say more about this soon because right now, pvp sam feels more like a sam (with the big skills having that ooomph factor in terms of damage) than pve sam with our wet noodle sticks.
