The only time I've felt like I was playing a villain character in this game is when I broke out of prison at lvl 1 (well there's the occasional bank heist but you pretty much get the picture)
Nice Hopefully this will help differentiate between rad/storm defenders and controllers as those sets have some heavy defense debuffs. Since defender debuffs are still unresistable it would be better to have a rad/storm defender over a controller to take down heavy defense sets.
A blaster with BU/Aim or a melee with BU/FA could still easily take them down but this is definitely a great start
A couple sg mates tested Ice tankers defense in i5 and with all his armors on as well as an application of EA, the tanker was hit consecutively by brawl (slotted with one acc SO). Build up/focused accuracy were not used.
