Any reds feel like commenting on this? He can barely clear through red without dying, and does it more slowly than any other jungler I've played. It gets slightly better once he gets an item or two, but his initial clears are awful. Is he really intended to be a viable jungler?
Yes. True, you need to get a good "smiteless" leash on blue in order to clear with some safety, but that is more of an issue of cooperation, not capability.
Why is Thresh labeled Jungler?
He's also not fully tuned yet.
