This is how I have my HUD setup
Minimalistic take. The idea is to stop fighting the hotbar, focus on the fight. All buttons are hidden to help me do so and memorized since all I do is play SAM ( for now... ).
Explanation: Hakaze is hidden on 1, pressing it highlights Yukikaze, so I know it's active. Pressing Jinpu or Shifu will turn off Yukikaze, but highlights Kasha and Gekko. This I apply to everything.
Ikishoten pops Ogi Namikiri buff anyways.
Senei shares CD with Guren anyways
ThirdEye / Yaten / Gyoten you never spam to need to know the CD.
Meditate or Enpi or Hakagureyou nvr spam to need to see them
Shoha and Shoha II are indicated by the Meditate Gauge.
Shinten / Kaiten / Kyuten, all u need is to see the Kenki Gauge for these
Fuga / Mangetsu / Oka / really are just AoE buttons I put on R F V mixed with Shift or Mouse buttons, honestly its really a 1 2 3 thing don't need to see them.
I already " Pre-Solved " Button Bloat " visually " on my Hud, it's all just properly hotkey'd. That's why it baffles me that they can't figure this out or even see a logical connection between so many skills to fix Button Bloat. It's obvious, it's a given if they but had anyone on their team that plays the game and the classes.
PS: No I don't use an MMO mouse either, I use the cheapest corsair with 2 side buttons .__.;
