Why do people buy this item over and over? I usually play as AP Nuker or CC, and so I have no use for it, but in the last game I played Caitlyn. I got one Doran's Blade at the beginning, just to get some health, that 10 Damage that can help, and that 3% that I can barely notice. What I noticed is that if the enemy tries to kill me, I can't use lifesteal to heal myself nor can I use potions in the early game to survive. Now I see people buying more Doran's Blades; is it really worth it? Would it be better to start with a Vampiric Scepter, play maybe a little more defensively, and save the money for the boots and for an Infinity Edge, for example?
So let's see: 2 Doran's Blades are worth 950g, and they give you +160 Health, +20 Damage and 10 life per attack. I see people buying 3 of them, but I usually buy 2 of them.
I would rather buy a Vampiric Scepter (800g) and a Ruby Crystal (475g) and if I wait 10s I can even buy a Healing Potion (35g). I know I get a little less damage, but what I noticed this way is that you can stay longer in the lane and if you are skilled with a Champion you can still get those last hits. And another thing I find useful: With my items I can build something later (Vampiric Scepter -> Bloodthirster). With the Doran's Blade I have to sell them later, and it results in another cost loss.
What are your thoughts on this?
