I would like to see his kit become something revolving around blood scent as his main passive while maintaining a hybrid damage kit, heres an example i thought of a while back
Passive Blood Scent: Warwick Gains Movement speed when moving towards targets below 75% hp (750/1000/1250/1500/1750 range)(1/2/3/4/5% at levels 1/5/9/12/15) for every 1% hp the target is missing below 75% (so 74% would only count as 1% missing), in addition Warwicks abilites gain additional effects on targets below 50% Hp, also gains heal for 20/30/40/50% (1/6/11/16) of damage dealt to targets below 75% hp
Passive Savage Wounds: Warwicks basic attacks cause his target to bleed for (2/4/6/8/10% at levels 1/5/9/12/15) max hp over 3 seconds as magic damage
Q Blood Hunter: Warwicks next basic attack deals an additional (6/7/8/9/10%) of the targets max hp as magic damage and heals for (80/90/100/110/120% of damage dealt)/ Blood scent effect: Slows the Target by 10-30% for 3 seconds based on how much hp is missing (max slow at 33% or below), in addition cd is halved/ CD 15 sec at all ranks, reduced by 1 sec every time warwick auto attacks
W Blood Hunters Howl: Removes all crowd control affecting Warwick and increases nearby enemies damage taken by (5/7.5/10/12.5/15%) for 2 seconds/ Blood scent effect: Targets below 50% hp will also be feared for (1.1/1.2/1.3/1.4/1.5) seconds/ CD 25/21/17/13/9 sec
E Feral Strike: Warwick leaps to a Target within (500/550/600/650/700) range and shreds them dealing (6/7.5/9/10.5/12%) of his max hp as physical damage (applies on hit effects)/ Blood scent effect: Warwick may activate again within 4 seconds to leap to the original target (1200 range)/ CD 18/17/16/15/14 sec
R Its more fun if they run (joke name but i couldnt think of anything better): Warwick lets out a blood chilling howl reducing movement speed of all targets within (2000/4000/6000 range) by (15/30/45%), then begins to charge (similar to sion ult) Sprinting over all terrain building up speed equal to 300% movement speed, upon entering range of a champion (similar to kled ult) will leap to them and supress them along with all nearby allies (roughly the range of yasuo ult) for 1.5/1.75/2 seconds dealing damage equal to 10/15/20% of his targets max hp as physical damage to all targets over the duration (applies on hit effects 5 times), at the end of the channel he will gain a shield equal to 80/100/120% of damage dealt/ CD 180/150/120 sec CD is halved if a target is killed within 3 seconds of the start of the channel/ Blood scent effect: In addition takes 20% of missing health as damage over the next 10 seconds (in 2% intervals)
Kinda feels overpowered, but this is what i would like to see for warwicks new kit, as i feel it suits what he should be, a dangerous drain tank that becomes more dangerous as you get lower
