FC Toon Advice

[Hailstorm]

Finally got enough FC to fill some gaps in my roster (just over 3500) and was looking for opinions...

Killer Prime
Ferryman
Baroness Redan
NOTB Ed
Cosmic LoL

...or save it for Angel or Gambler Ed?

I was leaning toward Killer Prime since he seems to be used quite a bit in the Frontier Dungeons.

I use Killer Prime the most out of those characters. Gambler is pretty useful as well, but I'd go with KP.

Killer Prime is the best option. NOTB Eddie is also a good choice if you need to buff up the amount of Eddies you have
