my suggestion and i'd like your opinion is to swap this "swap-screen arrow thing" of hero panel (when you choose your toons) into a "Grid-Hero Pannel". Or the option to swap between both, just like "Raids" have a swap to grid option.
Why? becouse personally im tired of moving arrows every time i swap toons. For my gamestyle it takes a long time and effort.
Give your opinon, dont trash the subject.
