Now, theoretically with this item, aren't you buffing lifesteal?
If I have 25% lifesteal and deal 100% damage to my primary target and 100% split two ways onto two other enemies, I'm going to be lifestealing off of 50% of my attacks.
Kind of. The problem comes in when you factor in infinity edge and critical strike - as those only apply to your main
So, if you go the typical IE/PD build with critical strikes, these secondary bolts are going to be far less than 50% of your average main attack damage.
If you go raw Hurricane / BT, builds for example - you will be life stealing more - at the cost of not taking advantage of the multiplicative power of critical strike and critical damage for the multiplicative power of Area of Effect attacks.
Basically - do you want to hit everyone a lot of times for a moderate amount of damage? Or do you want to hit one person a few times for tons of damage? But in the end, the amount you life steal actually kind of ends up to be around the same.
Will the Hurricanes extra shot prioritize champions?
