I wish invisible woman was good, because then we could run a full fantastic four team.
It's still not great since it's 4 of 1 class, but the synergies are actually pretty good. Also they all get bonus animations depending on which members you have, for example thing throws a rock during any sp2 and torch shoots fire for any sp1. And all 3 of the good champs balance well and make up for each other, just not invisible women. Torch is dps and miss counter, Mr fantastic has regen/power control and can give away prefights, thing is a tank with great immunities and an unstoppable counter. We were so close.
