Lets talk Zilean!

When I support, I love going Zilean, I feel he can turn a melee jungler into a carry. (Slow+Speed Boost to help with gaps).

Other times though I find him a bit under-whelming, a bit too niche.

Zilean + Panth/Wukong jungler is in my opinion has some of the single strongest synergy in the game. So strong I almost feel its an instant win.
And that feels more like abuse of raw numbers than actually out-playing anyone.

So in short, im wondering if we can tweak some of his kit. Can we decrease the slows/stuns but increase long term potency by maybe adding AP ratios, or even gasp having the number ratios be based on Zilean's current movement speed. I feel like this would allow buffs elsewhere without breaking Zilean because the primary movement speed items are Support Items.

Next Zileans bomb. Upfront it seems like a lot, and it can be quite damaging, but it also has a low ceiling cap on both the damage and skill needed. I want to be able to use Q-W-Q and not only get off a second bomb, but have a way to detonate them both at the same time. Think a passive attached to his Q where if both bombs go off at the same time the base damage of both is doubled. Just a thought.
