How Urgot could save Zilean jr.
1- the new slow mechanic is a failure. Half the duration for double the effectivity sounds fair, but with soft caps, people are getting 60-68% at rank 5, which is less than what's promised from rank 3's 70%. But, that's not what we're here for.
2- those dam bombs. Zilean is truly a 1 trick pony... unlike Nidalee, Jayce, and Elise who have 6 usable skills, most champions who have 4 usable skills, and a few who have 3 usable skills and a passive.... Zilean really has 2. He can bomb or ult. His slow only lasts long enough to try to make his 2nd bomb easier to hit... and with rewind not affecting his ult, it's literally JUST for that second bomb. But, with buggy code, the first bomb may attach itself to a creep.... no worries, just soublebomb the creep and stun anyway? Nope, 2nd bomb finds a hero or randomly picks a different creep... now you're out of tools until your next doublebomb.
But, Urgot has the answer: Urgot fires an Acid Hunter missile that collides with the first enemy it hits, slowing the target if he has his Terror Capacitor up. Acid Hunter missile-locks on enemies affected by Noxian Corrosive Charge.
There's already a function for allowing "missile lock." The nerf happened because people didn't like Zilean harassing so easily, so make the FIRST bomb a skill shot, but while a bomb is active, other bombs can misile lock to become reliable.
This is a step in the right direction. (His passive has always needed a change, his ult didn't need a nerf, and change the friggin slow back, or take it out. A 2 second 68% slow is worthless.)
