Is it worth building a Bloodthirster on any ADC now that the meta is shifting towards tanks?
I'll do some math, correct me if I'm wrong. Let's take as example an enemy with 3.000 current hp and 150 effective armor (after penetrationz).
A 
will add to an autoattack:
32 dmg if normal auto, 80 dmg if crit auto;
- 20 % lifesteal applied to the whole dps
A 
will add to an autoattack:
10 dmg if normal auto, 25 if crit auto + 96 dmg from passive, for a total of 106/121 dmg
if we consider +40% attack speed, we might get to a 150/170~ dmg contribution
- 10 % lifesteal applied to the whole dps
The dmg contribution on a single autoattack on an opponent with that effective armor sees outshining when he has 690 hp (for normal auto) / 1720 (for crit auto).
This is not taking into calculation the impact of lifesteal and Blood's passive / Botkr's active plus that of the bonus AD on eventual adcs' spells and who knows how many more thing, so it's very approximate. Not to mention that we see tanks stacking hp rather than resistances (making Botkr more effective).
All in all, is Botkr going to outshadow Bloodthirster for as long as tanks will keep seeing the light of day?
