1) his mollies are not supposed to kill. A simple fact that you can just open up a map, click onto any corner and send a nade knowing zero lineups to clear an angle is insane. Not to mention the post plant potential. If you plant the spike it looks impossible to defuse. Pair it with kj mollies and it's gg round won, just save there is no hope to defuse.
2) his rc car is not the worst, it's much better then sky's dog. It offers more visibility and will be harder to shoot down.
3) his stun is okay, nothing crazy, but it can be used to clear corners.
4) I disagree on his ult, it doesn't look that good to me, the area it clears out looks to be too small. It's fine as post plant/retake ult I guess.
