zilean rework

New zilean is still terrible, figured we might as well give him the skarner treatment and rework him until we get a balanced fit with his identity still in tact. This is mostly inspired by insomnia atm so pretty rough, needs input and suggestions.

passive, small clock divided into 4 sections, essentially every 4 seconds his autos apply a different debuff, those being stopping hp5, stopping mp5, small attack speed slow, small movement speed slow. These last for 1-2 seconds and are reaplied and have duration increased by .2 for each new auto attack at a cap of 2 seconds. Can gain multiple debuffs if keeps applying them

q-time attack, zilean attacks the enemies future, planting a bomb 4 seconds ahead of the present. The bomb is invisible until .5 seconds before detonation and applies a slow at 1 second before detonation. Aoe being just smaller than the size of a quarter

w reverse time- undoes 80% of the damage taken within the past .5 seconds of the target. targets next auto attacks for next 2 seconds applies zilleans current passive debuff(stacking with his own) and 20% of damage shielded per auto

e- fast forward. zilean, speeds time in a small aoe, increasing friendly healing, hp5, mp5, and cdr every second. can be cast again to root himself for 1 second and burst the hp5 affects. If auto attacked during this time he is rooted for 1 second and the ability ends at next tick.

r for next 10 seconds has no cooldowns(more like .2 sec between each), but after the 1st cast of each ability the following casts will cost 3% of his hp(additive, so using q 4 times would cost 9% of his hp and spamming all abilities 4 times would cost 27% of his hp).

What I was aiming for was someone who has interesting time based mechanics that has to focus on the past, present and future. He has good damage and harass IF he can predict where the enemy will be in 3-4 seconds. Great in active trades if he can time things well, and can sustain his team or lane in luls between a fight. R would just allow for him to get more shielding, sustain and damage off in a fight at the expense of his own hp. His q would stun if target was slowed by q, w could be applied to multiple team mates or make one team mate hella tanky for a few seconds, and e could be bursted multiple times for amazing aoe sustain.

Would be a great alternative to sups like janna, lulu, soraka.
