WTF you are talking about with high base damage? At level 1, you will probably have 600 hp, which results into just a 30 damage increase on Q and 15 damage increase at E. With 1000 HP it would be 50. Tell me, why this amount of damage increase would be OP?

He is made for the jungle where this is no problem at all for early levels. He might has some sustain problems but shield + passive should actually fix that.

Did you ever heard about kiting or CC? The thing which makes lifesteal completly useless? You have to use your brain agianst him, not button smashing. Similar to everyone thinks Yi is overpowered just because they don't use their brains.
