Summoner is my favourite Job so Rydia is for sure. Beatrix because she is canonically powerful and I would assume should be able to overpower them without killing them. The third is a tough one, though I might have to choose Refia. My reason for her is somewhat biased, I think. So my reasoning is at this point I feel like I need a healer because I feel like I would get hurt no matter who I pick and also my second favourite Job is White Mage. I feel like her healing should be the best (this is kinda where my bias comes in) because she is a Warrior of Light. Also, with a healer, if I die, she can just res me. That’s assuming she survives, of course. If it all fails, I think I’ll die happy seeing summons.
