I love the monster. Haven't played him much recently, but he does hold quite a special place in my heart, since he was one of my top picks in Season 4.
Currently, his win rate is around 48%, which in itself isn't too terribly bad, but given his relatively simple kit, isn't necessarily good either. This silence nerf certainly won't make him irrelevant at all, but does indeed further push away his viability, which is niche at best right now. Can we have some context as to future plans for the massive monster?
