Characters I've tried:
Trish: both peek-a-boo and low voltage:
I like low voltage because the hit box is so high on the projectile and while peek-a-boo saves me at times, I often trust in it and get hit by dive kicks blowing right through it. She also has weak DHC with Dorm. Not terrible but not great since you'r often forced to interrupt dorm early. Voltage can relaunch combo in corner with Dorm.
Taskmaster: horizontal assist:
Used like a beam. However hit box isnt very high and just never felt really effective over all. Can relaunch combo in corner with Dorm.
Iron Man: repulsor and beam:
repulsor is a nice situational GTFO and beam is pretty good assist. He also DHC's well. I'm just awkward with him so he's been in mind if i can get better with him on point. can do a relaunch set up with Dorm on point anywhere on screen with repulsor, and in corner with beam.
Sentinel: charge:
Speaks for it self, but I dont like using sentinel and he not big on his DHC's unless im in a corner. No relaunch capability with dorm.
Storm: whirlwind:
Whirlwind acts as a mid screen beam and push back, but doesnt reach full screen and it's not very high to stop jump ins. Does DHC well and relaunch combo in corner with Dorm
Really I'm looking for a way to cut off short jumping at range. Zero, Ryu, and Akuma just mess me up with their ability to get in at odd angles with VERY high priority and anti-advancing guard tactics. So I'm looking for one assist to keep away and one defensive.
