The ratio on Swain's ult actually isn't that low if you take into account that it ticks once per second, on up to 3 targets. Say you keep your ult on for the 4 seconds his Torment is ticking, that's 96% of your AP over 4 seconds, against potentially 3 targets. If you're in the middle of the enemy team doing that kind of damage, and healing up a shitload, you're going to be ripping through them.

Of course, Magic Pen is definitely good on him because all of his damage is Magic Damage. If you wanted to go a heavy MPen build, you could go RoA -> Sorc Shoes -> Abyssal -> Liandry's -> Zhonya's -> Void Staff. I feel it's a mistake to leave Deathcap out of his build, though, because Swain actually has great AP ratios (384% AP ratio with a full Q and 4 seconds of Ult).
