well is not that you only have 4 items i mean and are 6 items you always need to make a build with 6 items and you leave there doran blade that should be not there......remenber do a nice build and when you put in the bloodthurster you need to a armor for defender i can only see banshee`sveil beacuse he is a tank so he need HP put is so wharmor armor or force nature that all

Well i forgot to put blood thirster after trinity force sorry for it...

where is the dmg ? you have trinity force but you cant have another dmg and not to much lifesteal only the spell and you need a few armor. do that and i will voted for u , anyway that is the only armor and dmg with a few lifesteal for you can old in the field vs dmg dealer
