The problem is that b12 ends his pressure. Most of his pressure gives the opponent holes to get out anyways if they know the MU. When people play patient and wait for the right moment, they can get out.
The best thing about Dualist is the sheer amount of meter he gets while pressuring. ITs probably better than both FF and DF.
dd1 builds meter
orb build meter
orb cancel builds meter
block pressure builds meter
If you look at in on paper...that can make him scary as he doesn't need to be afraid to use meter. When I play
@Pig Of The Hut or
@AK XEN0M0RPH I realize how hard dualist is to use. DF is so much more viable simply to the upgrade he gets to footsies and zoning with low fireball.
