Its far too restricting compared to how it was in Endwalker.
  1. I used to split Meikyo Shisui and Tsubame usages between AoE packs. Now I can't.
  2. If a pack dies after using Tenka Goken, I lose Tsubame. So now its better to Hagakure instead of using Tenka
  3. If Meikyo is about to cap but I'm holding burst, I now have to always hold Meikyo instead of making my own decisions

The gist of it is, the change makes several assumptions about when I'll want to use Tsubame and its not always right. Not to mention it gives me a buff to use Tsubame and we're seeing buff cap issues more often lately. Why add yet another buff when it wasn't needed before?
