Is top lane Hecarim OP?

Was talking to a friend the other day while we were playing, and I think he had a few hecarims that did well top, and had this idea that he's too strong and needs to be nerfed. Me personally I don't think he is, and I don't play him so it's not like I have some bias. There just seems to be too many things that can stop him, ranged top, cc, exhaust, ect that at least to me makes it seem like he's just something new that people aren't used to seeing, nor know how to stop, thus their opinion he's OP.

But am I wrong? Does he need to be toned down, and if so what would do it in a way that still makes him a strong pick. While I'm not playing him, it's a breath of fresh air to me seeing different champions being played in odd roles. Hec top, Naut support, Urgot mid is all really cool, and different from the past year or so of rather meta picks. But let me know if I'm wrong, and how you guys would fix him if he is indeed too strong.
