ITs are very strong except for Magma, you most definitely need Veers (leader duh) and Starck (very good buffs) the problem is you now have 2 great attackers and 2 great tanks to choose from and now it depends on your playstyle
Shore is great, taunt as well as heal and crit immunity is hard to look past so he automatically gets dibs, Snow has a extremely powerful aoe he can keep using over and over, that leaves Storm and Death, Storm is a very good tank before Shore thanks to his defense up as well as 30% defense to IT allies, giving all allies a solid 80% defense, Death however has daze and aoe dispell so he is good too, but the issue is Death is a painfully long farm.
