I think I have a very different view in what button bloat is <_<

For context, Shoha II prior to making Shoha for SAM having a cleave aspect, was just an AOE version for the sake of it and cost the same as Shoha I, which has been rectified thankfully. That's what I see as "bloat". Same kind of applies to Senei/Guren for me.
(I do not consider basic spenders as such, but rather actions with significant cooldown or requirements of time spent preparing matching one).

Oblation being decoupled from TBN allows for independent usage rather than having an opportunity cost tied to TBN, which is why I did not consider it bloat. Maybe a bit flavourless if we look at it just from the effect, sure - but I didn't see it as bloat.

The ability to spot mitigate multiple people, especially without jeopardizing myself, has helped me saving people a lot of times where I just said "Paladin could never do this". Very basic effect, but the flexibility is fantastic.
