Don’t take him up to r4He has some good abilities and I like him but since your roster is still growing I’d wait for a better champ
I disagree. If you can play his rather unique style well, he is a fantastic skill champ. He just requires an unusual style, so he takes more work to get used to than most want to put into him. And I will admit, he is not a Quake or Ghost level champ, so many may think he isn't worth the extra effort like they are. However, he was my second 5* R4, and while I've had better champs I've since taken to R5, he is still a valuable resource in questing, especially when I need a class-specific roster. If you can get used to throwing heavies immediately after he triggers the concussion on his current targeted attack, it is basically a free heavy amd immediately sets the next target. It makes it relatively easy and quick to get to the 5th concussion and get that "super concussion" (I forget the actual terminology in his description). He can end many fights pretty easily that way.
I pulled him recently as well. Without the dupe he's still pretty good
