Ouch, I'm like level 75ish, and I'm not going to get any more spots 'til 110? Ah well. Still, I like helping people and I think people like having a helper squad that has 3 evolved 6*s (though I often look for Edelweiss/Toad Lily combo for any map that's going to last a while and has lots of nests, like the Mission 12/13 maps; event maps often can just be powered through with high-power squads), but all 30 of my friends have a last-logged-in of 1 day or less, so don't see any reason to kick them. If I notice any1 consistently nuking raid bosses on the other hand...
