User blog comment:Mich, Michele & Kuhla/Future Units Preview/@comment-3547897-20150616055711

Now that I'm thinking more straight, I'll review all 3 again.

Michele - Fantastic Arena lead. The Crit buff is small but with everything else she brings to the table, it's a fair exchange. Other than that, not much to say

Sagavehl - Now that I look at it's abilities more closely, he's by far the worst of the batch since Melchio outright does the status cleanse better. Sure, his LS gives 40% boost but only to HP. Grah/Ark/Owen boost 35% to ALL parameters plus they're free. The %HP buff on his BB might seem OP but only on paper. In reality, you're only gaining about 6.25% extra HP. The Spark debuff I can't comment on since it's relatively new.

Melchio - Ah... What everyone thought to be the worst is actually one of the best. His godly 48 DC makes him very suitable in Arena as does his BB which gives him an advantage over Sagavehl. By the way, Melchio has lower BB/SBB mods than most units is because the elements on his BB/SBB will make you immediately do high damage.

On to SBB, the 30% Atk -> Def is pretty strong, almost as strong as Aurelia's Rec -> Def buff. Now you might be asking "But 70% is far from 30%. Why is it almost as strong?" Well to that I answer: Atk is the easiest stat to raise. Spheres + Imps + Breaker typing + LS + Buffs will give you such a huge boost in Atk that it'll make you nigh invincible. Since it stacks with Kanon's Def buff, that's also a plus.

His ES is what makes him perfect. Unlike Edea who needs a status null sphere, Melchio can enjoy Status Null and a param increase from his White Armor sphere. It also makes Sagavehl's ES useless.

tl;dr - Melchio > Michele > Sagavehl
