Warwick Remake Suggestion V.2 - Improved!

Passive
Warwick's attack speed is increased by 20/40/60% (at level 1,9,16). When Warwick drops below 50% health, for 10 seconds he gains 4-14 additional magic damage to his basic attacks, and heals himself for the same amount (maximum of 4 stacks, stack stays for 3 seconds, stacks stay even when warwick changes the attack target). If Warwick gains a kill or an assist during this time, the duration of this effect increases by 3 more seconds (Cooldown: 120/60/30 seconds).
- What Changed?:
- He now has attack speed bonus as a passive, but not that much.
- His basic attack - magic damage healing thing only procs for short amount of time when he drops below 50% health. This along with the base damage nerf of his ult makes his 6 level gank not that much of a threat now, but I buffed him with his new W and tweaked E to let him gank a bit pre-level 6 (although his pre-level 6 gank would still be weak).
- Overall, this is a bit NERF.
Q
Deal 75/125/175/225/275 (+1 AP) or 8/10/12/14/16% of enemy's max health as magic damage (whichever is higher). Warwick heals himself for 60% of damage dealt. The healing amount increases according to the lost health percentage of Warwick, which can increase to maximum of 100% (of the damage dealt).
Mana Cost: 60/70/80/90/100 Cooldown: 8/7.5/7/6.5/6 seconds
- What changed?:
- healing changed to "always 80%" -> "60%, but increases to 100% depending on Warwick's missing health"
- Mana cost reduced at all levels by 10 (because my Warwick Remake's E also costs fair amount of mana now)
- Cooldown changed to 8/7.5/7/6.5/6 from 10/9/8/7/6
W
Warwick howls and creates a hunters field around him for the next 6 seconds. Any ally champion, except Warwick, in the field moving in the direction of enemy champions in the field gains 10% movement speed (field is large). Additionally, all ally champions (again, except Warwick) heal for 5/7.5/10/12.5/15% of the damage Warwick dealt to enemies during this duration over 3 seconds.
Mana Cost: 30/35/40/45/50 Cooldown: 24/22/20/18/16 seconds
- What Changed?:
- Everything. Removed his attack speed buff to allies thing, instead gave him healing buff to allies which benefits the team more equally (Now still useful if your team is AP - based instead of AD/AS - based)
- This skill could be still useful when your team is trying to get a Dragon or Baron together.
E
Passive: Warwick senses enemy champions below 50% health. If there is any, Warwick gains 5/10/15/20/25% movement speed (does not share their vision).
Active: Warwick lets out a howl, and for the next 8 seconds he instantly shares the vision of sensed enemies (not stealthed enemies), movement speed bonus is doubled, and the duration of any Crowd Control Warwick receives is lessened by 20%. If there is no longer enemies below 50% health in the middle of this effect, the movement speed bonus and tenacity bonus quickly decreases.
Mana Cost: 60 Cooldown: 20/18/16/14/12 seconds
- What Changed?:
- No longer shares enemies' vision now unless you use the active, which costs mana and has CD.
- When activated, movement speed bonus is 10% higher than current Warwick, and now he gains 20% tenacity.
- When enemies below 50% health are no longer around, now Warwick's bonus effects decreases over a short time instead of current Warwick's "have them for 2~3 seconds and then suddenly disappearing".
- This is my most favorite idea among my Warwick Remake skills. The current problem is that "you basically turn on E all the time from mid game on, and from one point on you kinda feel like you don't have any E skill at all. You can't feel its presence - you start to forget you are a champ with 4 skills." This changes that a bit.
R
Warwick suppresses an enemy champion for 2 seconds, dealing 100/225/350 (+2.0 bonus AD) magic damage, and gaining 30% life steal during the duration.
Mana Cost: 100 Cooldown: 110/90/70 seconds
- What Changed?:
- Suppress duration increased to 2 seconds from 1.8 seconds
- Base damage nerfed to 100/225/350 from 150/250/350 (Bonus AD ratio stays the same)
- Mana cost buffed to 100 mana at all levels from 100/125/150 mana.
Still having hard time to give him a legit new W skill that lets him gank a bit more easily pre-level 6 since I nerfed his level 6 gank a lot, but at the moment I'm satisfied with what I did above. Hope Riot member reads this and even if he doesn't follow what I did, he could at least get some really cool ideas about his remake. I'm actually pretty satisfied with Warwick as he is now, but I do believe he could do better. :P
