This is news?
I do 170 AP+ combos all the time with Dante. I thought any other decent Dante did it too. (All the ones I meet parry cancel and try to do the kill-confirm.)
Slash-Slash-Slash-Full gun burst-Dash-Axe-Gun cancel-Dash-Upwards swing-Slash-Slash-Up slash-Up slash-Gun burst-Dash-Slash.
Optional: Parry right before you do the entire combo.
You can go for 2 gun bursts at first, but you'll have to cancel the second in less than midway, so you can only get about 20-30 AP from guns alone.
My most is probably 183 AP. (Happy accident with the gun shots connecting in the air)
I don't use any of those wiener moves, either, not parry cancel or this bold cancel bull crap.
I like that you're proud of your Dante, though. Especially since you try to fight fairly, or so I hear.
You'll have to get better with another character eventually, though.
