me too, can probably use only 1x atk up to lvl 15 or so for those with maxed out 6 and 5 star squads. the last time we had an even like this, the bosses were lot harder. i think that was during the 1-2 months in the late winter when all the raid bosses were super strong.

also, isn't the 20/3x better use of neckties than the 40/5x?
