I think Victor’s defense buff is nice. The Mana Regen bonus is helpful to get to 6 tiles but any further increases aren’t super helpful since you will be ghosting for 6 in the end anyway.
So the question is: dot + defense vs sniping.
My impression (with no beta experience) is that kageburado is better to take down a tank in the initial stage of the raid… Victor’s dot isn’t going to kill Guinevere fast enough but front end damage would.
In the end of a close raid, I’d prefer Victor’s dot/defense vs someone like marjana since 225 is going to take a couple hits as well… And without the defense buff, kageburado had less chance of surviving a corner special (something like 450% front end damage)
Neither is bad since very fast is such a bonus, but I’m going to go with kageburado since the first stage of the raid sets the tone for the entire fight and getting the tank down quicker generally will mean a more favorable end stage
