Bless my friend for being good at math - he mathed out that it is currently impossible to maintain group quickness as untamed, even with 100% boon duration. (edit: it is possible to almost maintain full quickness on self due to 2nd major)
I tried going with
hammer 3, hammer 5 (habit from fervent force days) pet f1-f3 during those 2 buttons, unleash, ambush, hammer 2, hammer 4, unleash, swap
axe 2, axe 3 (also pet f1-f3 if they're back), unleash, ambush, axe 4, axe 5, unleash (pet f1-f3), swap
It's not that much different from the muscle memory I developed.
BUT then I tried going with unleash-ambush immediately and waiting for it to come back before doing it again and weapon swap AFTER the 2nd ambush. And boy, did the "cooldown" of unleash pet/ranger disagree with me. ....On top of STILL being unable to provide full quickness. Nope. That's janky for me.
