you only need to cast myrmidon's once. ever. and then you have the buff forever. you can click the icon off, you still have it. just click your shoulders once and then you're done.
you only have buffsize=2 so your third buff is never going to fire. but i wouldn't put a song in buffs like that, just work it into your twist.
wish i knew what songs you have. your ooc twist is 1 2 3 4 5 and your combat twist is 12 5 2 12 3. i assume verse is song 12? there is no need to repeat it with only a 4 song combat twist because it's not going to be ready where you have it listed the second time. which shouldn't matter with the recent changes to how eq will skip songs if they aren't ready, but still.
from my own experience, KA bards and mq2melee do not get along. so if you can set melee to 0 and get anything out of there and into KA, you'll have a lot better chance of making things happen as you want. KA can do everything melee can.
your nature's melody and songblade should fire in the buffs section. for whatever reason, i recently had to add a dual tag to my sword to stop it from spamming. i also put a me on my nature's melody with a condition check to see if i had recently died.
Code:
Buffs3=Nature's Melody|Me|Cond10
Buffs4=Rapier of Somber Notes|Dual|Symphony of Battle
Cond10=!${Me.Buff[Resurrection Sickness].ID}
as far as dicking around in the twist section ... idk, man, i'd just delete the entire thing and let KA write it as it sees fit!
