3 things I need to know about Arans

1) I was under the impression that Final Blow, like Combo Smash and Combo Fenrir, does not get a damage reduction against mobs. Assuming that's true, without SE (or at a low combo count), Final Blow should be worth using if it can hit 2 or more monsters. At a high combo count and with SE, you'd probably want to hit 3.

I think Final Blow gets a damage reduction. It seems to do less damage when I use it on mobs than 1v1. I wouldn't know that well since I don't use it often.
