Swain Balancing

I feel that Swain need to see some re-balancing as he is becoming quite over powered in toplane and mid. His ultimate gives him far too much sustain, DOT in team fights, and in lane; he is too much of a bully with his range, damage, cc, and tankiness; and provides too much power for a single character in a team. I think Swain is becoming the new Ryze of toplane; he should probably be balanced for the same reason as Ryze did. They even have a similar kit, with a snare, regen, and magic damage. They both were able to poke down normal tanky top laners with magic damage, and can solo every lane opponent. There is not much counter play in the toplane, unless someone were to go out of their way with an odd mage counterpick, which would reduce their own utility for their team. I just think that many top laners will feel better if he were less of a beast.
