Regen are Heals too~
And uh, no. Def up is rather crappy, and certainly not the main use.
30% Def sounds impressive, but isn't the same as damage cut. It is significantly worse. Considering uptime, you'd probably be better off bringing Baphomet for her -10% Atk debuff. Are you going to? No, no you won't. With her skillset, you wouldn't bring her even if she was SSR.While true, all the damage in the world won't matter if you're not alive. For example in Advent Ragnaroks, you're going to need to survive a couple of turns before and after at least one Overdrive, before you can Full Burst to end the fight. Neither Svarog nor Mars will help you accomplish that, although they do make the fight significantly shorter overall.They can do both, though. And they should. Getting Atk+, Dbl+ or Affliction Rs will boost a new player by a fair bit.
And the sooner they can do R3s, the sooner they get access to SR Accessories. Which are usually complete garbage, but at least they're great fodder. With someone like Amaterasu helping you get past Wave1, you should be able to clear Accessory Quests much faster.
I suppose we agree to disagree?
