Sorry Riot, I Do Not Like New Zilean.
I gave him a few tries on PBE and it wasnt too bad, the first game was hilarious but the rest were meh. So i decided to play him today and he is actually not much fun to play. These people were actually pretty good so getting hit by 1 bomb they would run immediately before the second bomb would hit them. So i tried leading them well the bombs takes so freakin long to land they would just spin around and run the other way. No matter what i tried these people would dodge the second bomb, once they knew what i was doing they would just run. The only good part of the rework is the movement speed boost, which is really fun to use on a Sion, but other then that i was useless. Anyone with Mobility just charged straight at me, even if i stunned them i still died.
So i probably wont play him anymore but there is a way to make him more fun. First make the bombs stick to champions better, i have both played as and against Zilean so i know that dodging his bombs are incredibly easy, sometimes he can hit you almost directly and it still wont stick. Second increase the throw speed so the bombs land faster, when someone with no boots can dodge all your bombs just by immediately running away before it hits, there is a problem. Third and lastly, reduce the mana costs of his Q or W early game, not only is it freakin impossible to hit the double bomb but it costs a ton of mana to do it.
I could be wrong and its just i suck but he was pretty much no fun.
