Something I’ve found when playing Street Justice is that Sweeping Cross starts feeling a little superfluous once I have Spinning Strike, and a lot superfluous once I have Crushing Uppercut. As a combo finisher, I don’t want to use it before I hit level 3 combo, but once I have level 3 combo, the other two finishers are almost always a better choice to spend it. This means I rarely actually use it, which is a problem as it’s one of the only two AoEs StJ gets.
To solve that, I think the easiest solution would be to make it so if you have level 2 combo or lower, it builds combo instead of spending it. That makes it much easier to use in a chain at higher levels, and improves StJ’s anemic AoE potential.
