Couple DB + crit ring mechanics questions

I mean the mirror image hits. they look like they are 2 blade 1 dagger, because the one in the middle is stronger. the part of my attacks is always 2 dagger 1 blade.

it's as if the dagger/blade is determined by a mod 2 of the attack number; and since triple stab is odd numbered, the MI hits are reversed on the weapon.

Well, since attacks on Dual Blades always alternate, the MI hitting 2 blade 1 dagger would make sense, considering the last hit on regular TS is a dagger hit. That's probably what MI does for all skills, not reverse the pattern, just continue on with the regular pattern, ie; (TS)Dagger > Blade > Dagger > (TS with MI, continuing with pattern)Blade > Dagger > Blade.

So instead of 4/2, you get 3/3 because of the Dual Blade attack pattern.
