A rather complex hero to mathcraft about but lets give it a shot!
Assume we are facing a team of Split damage
, Warwick has no resistance bonuses, but he can gain health 3 ways: through his passive, Q and Ultimate.
Level 6 WW has base stats of 1050 Health, and 56 Armor and 57 Magic Resist (runes and masteries)
Now lets analyze and make assumptions on what happens when he gets into a early team fight at dragon.
He Q's someone for 10%(assume they have mr) of their health (roughly 1000) so his Q does 100 damage and heals him for 80
He then autoattacks 3 times to gain 76
He takes alot of damage and decides to ultimate someone hitting them 5 times. During this time he is considered to have full stacks of his passive, and 30% lifesteal... so he will gain roughly 180 + 80 health for a total of 260 health
Immediately after his ult he Q's them again and heals for 80 again
, before dieing.
So far he has gained a total of 496
With this in-mind we can then assume that he effectively has roughly 1500 Health and 60 Armor and 60 MR
... with no items. Pretty good
Our next goal will be 2000 hp, so we grab a
Level 11 with
Will have 1850 Health
With 118 Armor and 123 Mr
Another team fight at dragon...
He Q's for 20% of max health (2000) 400 damage which is reduced by mr to 200. He heals for 80% of this
He then autoattacks 3 times again healing for 108
He Q's a second time healing 160
Then he ults Healing for 270 + 120 = 390
He Q's again 160
So effectively he has roughly 1000 bonus health
from QX3, 3 autoattacks, and his ultimate.
So now we are sitting at 2850 Health and 118 Armor and 123 Mr
Our next goal will be 200 Armor and Mr
Will have 2580 Health
and 265 Armor and 270 MR
A teamfight at Baron this time: in which he will heal for 1000+ (see above calculations)
Giving us a total of roughly 3500+ Health and 270 Resistances
Nicely balanced out.
