Do not change nothing of Warwick's ult and E. These abilities make him UNIQUE. I think he needs new passive and updated Q. Passive's Damage is inutile cause of Enchantement Devourer damage stacking. Q has a low range and massive mana cost. Make him new Q - usable to ganks, but let still the healing. It's utile to kill the frog at level 1 while jungling. Decrease mana cost, increase the range. W is also cool and makes pushing easier. Do not change it as much . I play frequently warwick, he is one of my main champions. As him i can carry games easy and kill champions quickly. He is one of the champions with highest DPS . His burst magic damage on hit makes him distinct of all physycal melee carries.
Do not add him skillshots. The game must contain champions which are easy for begginers and Overpower. I thik you nerf all OP champions. I remember for example the nerf of Veigar(He was very cool and f***ing OP) or the nerf of Akali's ult range and detonation of ,,Mark of assasin''. You made Veigar's Q skillshot and it made him very bad. He was easier to play before the change. Each nerf reduces the champion's win rate. These champions who need to be updated must be more funny and easier to play. For example Ashe was stupid and bad champion. I didn't like her. Now, before the passive and Q updates i enjoy playing as her. She's very, very OP. Tristana too. Updated AP Tristana is a MACHINE. She was a junk before the rework. These are my ideas on Warwick:
Passive(Innate):
Hitting neutal monsters or lane minions with basic attack will cause them to burn for 25% of target's current health as physycal damage over 3 seconds.Warwick heals himself for 80% of that damage dealt.
Q - Hungering strike
Active: Warwick strickes an enemy dealing 10% of target's maximum health(+100% bonus AD), slowing it's movement speed by 65% for 2 seconds and reduces it's armor and magic resist by 30%.
Range:650
Cost:40/45/50/55/60 mana
Coowldown:10 / 9 / 8 / 7 / 6 sec.
I added AD scaling, armor and MR reduction, and additional slow at all ranks,because he must be strong and gankable early game. It need also VFX update. It sounds like WW's critical attack.
W - Hunter's call
I didn't change the stats of the ability . I added new effect.
New effect: When Hunter's call is active Warwick increases has 20/30/40/50/60/70 bonus armor and 15/20/25/30/35% crowd control reduction.
I think it will protect Warwick from high damge from ranged AD carries while using the ability upon pishing or lane farming. Crowd control reduction is pretty good upon fighting hard CC tanks or mages with stun or massive slow. I decide to still half AS bonuses to nearby allies, because it's usefull in team pusing or while ganking.
E - I didn't change this ability. It's very cool. He can move quickly toward enemy champions and he's able to slow them with Frozen Mallet or BOTRK.
R - This is the main skill of WW. It deals massive magic damage, does good ganks and it's very powerfull in teamfights. Remember Riot: Do not change it as nothing.
Warwick is also strong in top lane. He is the best counter of Riven. I beat her each time when i play as WW on top.
Warwick IS one of my favorite champions and i love him such as is it, but i will enjoy any changes except of E, ult and added skillshots.
