MY GOAT 🔥

advanced mode ST does not use bow shock / blasting zone at all. same for simple mode. they're only used in AoE it seems. No mercy is still used after 1st GCD in both modes as well.

From just a cursory look at GNB and WAR changes: LGTM, I especially appreciated seeing all these Options changes seemingly without reusing IDs.

Regarding Bozja:
This all looks good, and some of it is still fresh from me helping with bits of it, but just taking the opportunity here to note some things still missing.

• No other Field Operations would currently work, even if features were added as the Presets code does not even draw them.
  (not that there are other Field Operations currently added into the code yet)
• This will not un-holster Lost Actions if needed.
  (perhaps this should be explicitly mentioned?) (fixed in 4bd6647)
• This will not check amount-available for slotted Lost Actions. (fixed in 4bd6647)

Because of the last 2 items there, enabling more Lost Action options than just what the user actually has slotted leads to lots of actions just not being done.
Especially considering it is Bozja: I still think this is more than adequate for collecting feedback while the rest is worked out.
