OK, so I've got a level 96 Filir, and I'm torn up between which homunculus to choose as Homunculus S. I'm an MVP build, except that I started my Filir when I was a different build, and I've gotten really attached to it, so I don't wanna kill it and start a new one unless completely necessary. My prime choices would be either Eleanor or Dieter, maybe Sera except I'm really iffy about her sprite xD. So my question is, if I turned my Filir into Dieter, would this have any negative impact on ability to help in leveling/ fighting MVPs when it hits 150? I know it'd have low HP/SP, so I'd keep it mostly around for mostly around for Pyroclastic/Granitic Armor/ Volcanic Ash, maybe AOE? Other choice would be Eleanor, but I'm not sure how good she is for leveling/fighting MVPs. Also, I'm probably gonna move towards PVP at endgame. Any help appreciated, thanks.
P.S. My Filir stat's(without buffs) are:
HP: 7831
SP: 677
Atk: 120
MAtk: 306
Hit: 382
Critical: 26
Def: 217
MDef: 157
Flee: 255
ASPD: 184
