I actually used to use Sakon/Ukon in my main team until I got Gakido at around level 65ish. Even now I swap Gakido out for them if I need some more DPS and attack.
That said, Sakon/Ukon were easily replaced by the overused Tobi before his nerf, so naturally they'd be more on the underused side. This post was last edited by Dosu at 2017-2-9 00:28
