your big improvement is when you get your toci's to complement your dot and CDC and also athos legs are a pretty nice upgrade. You're pretty much on the right track, however I do carry anguinus and mantis eye for ws just in case I do need it (I dont have ig-alima's atmacite though) on prov watcher, maddening radiance or something like Ig-Alima.
Nishida: Get frightful roar because Bilgestorm wont last forever. P. Embrace for Main Healing if you're actually needed or that or a backup cure behind fruit if you're soloing in abbsyea maybe.
B. Typhoon and Vanity dive are your current /thf spells if you do that you dont have to get vertical cleave if you're completely leeching 99.
Get Mind Blast (potent paralyze) and the Walrus move(makes fast cast and also a good paralyze)
Going to guess you're going to steer clear of proc'ing blu in VW and abbsyea since you dont have those.
In VW and in fast killing groups(normally) I set dex stat spells in place of where my proc spells would be. Frypan Headbutt Goblin Rush Battle Dance Whirl of Rage then remove them for EV or an HQ proc (sometimes, killspeed can be too fast to warrant even that)
Triumphant Roar when you dont have stalwarts tonic in any event you're doing
Lastly Pollen for skillups!
Can you use whirlwind durs over +2 pants for Heavy strike?
