The introduction of gear from the 85-90 update and some recent tweeks and changes have me reconsidering how we use Finishing Moves for Damage, and I'd like some input. This thread will mostly discuss ideals, so explanations like "I don't have AF3+2 hands" are tolerable when asking for advice but not when arguing about ideals.
Options as I see them, complete with their enhancing gear:
Building Flourish - Consumes up to 3 FMs for varying results. Effectively Berserk for one WS if used with 2+ FMs. Crit rate and Berserk if used with 3+ FMs.
Climactic Flourish - Consumes all FMs and forces 1 more FM than that to crit with Damage+20%.
Striking Flourish - Consumes 2 FMs and forces the next swing to Double Attack with a 50% Crit rate.
Wild Flourish - Consumes 2 FMs and "primes the target for skillchain." Can miss, and only works with level 1 properties.
Reverse Flourish - Consumes all FMs and returns TP based on the linked formula. 26/40/57/77/100 TP with 1~5 FMs. Useful for making self-skillchains, and generally considered the most efficient way to use FMs.
At 75 the simplest, most efficient, and most reliable way to turn FMs into damage was just to go Pyrrhic -> 4~5FM Reverse -> Evisceration -> Darkness. Committing all of your FMs to Reverse Flourish meant that no other DD Flourishes were considered. At 90 the game is different because A) we have Presto and B) we have AF3+2 hands and C) Flourishes III exists.
Valuing Reverse Flourish at 90:
Opening Weaponskill -> Reverse -> Closing Weaponskill -> Darkness (30 Skillchain Bonus with AF3+2 hands).
Generally you close with your stronger weaponskill (Closing Weaponskill), but you could have spent your initial 100TP to open with it. Therefore, Reverse Flourish is worth Opening Weaponskill + 1.3*Closing Weaponskill.
However, it's entirely possible to self-skillchain with just 3 FMs these days as long as you don't use too many JAs between the first and second WS. WS TP return + 2 attack rounds with Saber Dance + 57 TP generally will get you the 100 you need for the second WS in time to use it and self-skillchain. With a little timing and spell Haste (no marches required), it's possible to self-skillchain reliably this way. It's slower than a 5 FM reverse though, so it's a liability in party play.
Leaving NFR out of it, how do we use the extra 2FMs best? These are the problems I see:
1) Building and Wild are on the same recast as Reverse, and Wild has a longer recast than it should.
2) If you spend the other two FMs on something like Building or Climactic, you're going to have to be buffing the opening rather than closing weaponskill.
3) Anything that you do has to offset the 3 seconds you lose by using Step + Flourish.
At the moment, my best solution is to go Step -> Building -> TP more -> Presto -> Step -> WS -> 2x round -> Reverse -> WS. It runs into Problem 2, but I think sticking more JAs between the two WS would make the skillchain unreliable with only Haste and I'm not sure the attack and extra defense down offset the 3 seconds I spend on Step -> Building.
