I agree that it's oppressive -- that's what Win'Gul is meant to be. But if it's too much, I'll consider fixes for that...
 * The AP boost was way bigger originally, but I deemed Voidbringer too accessible and had to gut it. I wanted to keep the effects though.
 * Q and W are only spammable when leveled up. W is meant to have that minefield-like effect (and the slow is really pitiful), plus 4 second cooldown, I wouldn't say the succession is too quick. The on-cast nuke though, I agree, gives him way too many nukes.
 * E... I just realized, you're nearly true. Win'Gul gains 1 Essence for casting, and 1 for each minion he killed with it. Killing an entire minion wave leads to +7, hitting a champion is +1, which makes +9, but the setup needed..?
 * R is meant to be an all-out attack, but in practice it looks underwhelming, it's right. The combo requires 6 seconds of sitting on your opponents with no such thing as other targets soaking damage. The damage sounds huge, but it's a bit hard to get it all off on a single target (The Voidbringer boost might be OP).
