First ticket gets me... Mareeta! -Spd... At least she might be good fodder if I ever get a better copy of her?
I mean you gotta be certain the unit you would give FB4 to has great speed, as we discussed momentarily ago which units could make great use of it. Otherwise, she is another unit that can also be foddered for null follow-up.
And Mia is the only unit that can get both, considering she's the only unit with FB3 as a skill. Though still pretty debatable on how well it synergizes with her.
