SOULFIST has so many structural problems with synergy. She depends way too much on engraving runes. In PVP mode, she is basically F-tier rank without engraving runes.
Hype mode level 1 is completely UNUSABLE in both PvP and PvE.
Hype Level 2 helps to bring the performance gaps but it last only 1 minute while many martial art fighters like Striker and Scrapper can spam and deal consistent damages with lower penalties.
Hype Level 3 is a nice buff but it is way too short and has high penalty cooldown. After every match, her Hype mode doesn’t reset. You are forced to play safe and delay until it reset which takes away all the fun of Soulfist.
You are forced to play a skill shot to initiate the fight. If you can land your skill shot, GOOD if not you become a sitting duck waiting to be slaughtered.
I used to see Soulfist players in PvP but now from Ultra 8 tier and UP SOULFIST players are basically GONE. In 50 matches, I saw only 1 Soulfist player. If you look at the top ranks, no body play Soulfist anymore.
The best way to fix her in PvP is to reset her Hype Mode cooldown after each match so she can have a fair fight against other overpowered characters.
Overall, Soulfist is not fun to play in PvP mode. She has high learning curve and much higher risk compared to other characters. I would not recommend new players to choose Soulfist especially in PvP. Soulfist is ridiculously UNDERPOWERED
