Joker's trait is still ass. They should make the HA's last indefinitely. If that would be OP, then they can just tone down how much of a boost it gives you. I also had an interesting buff idea for Grundy. What if you could stack all of his trait upgrades? Like once you get each one, they persist. That could be interesting. Also before I knew how his trait worked, I was hoping you could mix and match. Like start with power lv1, and then go to health lv1. That way instead of getting to lv2 on one, you can get one of two.
