Each expansion I get hyped and also worried about more skills.

I'm now imagining a poor sprout switching to SAM for the first time and seeing three Hakazes on their hotbar. 11, 122, 133 or whatever would work, of course.

I think the idea would be more that we adjust the way the actions lead into each other so you have a more equal number of choices at any given GCD, rather than we necessarily clone PvP's more button-efficient but still pretty much **** imitations of a combo onto PvE as well.

At present, the first GCD effectively gives access only to Fuga, Enpi, and Hakaze (3 choices).
Enpi simply puts you back at the start, but otherwise your 2nd GCD then moves towards Yukikaze, Shifu, and Jinpu (3 choices) or Mangetsu and Oka (2 choices).
Yukikaze, Mangetsu, and Oka finish their mod cycle, but Shifu and Jinpu move you on to only Kasha (1 choice) or Gekko (1 choice), respectively.

So you have anywhere from 1 to 3 weaponskills buttons outside of Iajutsu you can actually use in any given GCD... while spending 10 such buttons for that opportunity. That's not great. It's not DRG level bad (spend 9 of 10 GCDs in ST or 2 of 3 in AoE with one choice, and therefore actually no 'choice', and still only 3 choices in the remaining GCD), but it's still pretty bad insofar as button efficiency.
