User blog comment:Zilla4444/The Sheen/Trinty Force Dilemma/@comment-74.196.101.111-20120702092826

sheen/trinity force doesnt give much anyway, most champs on average have abot 100-110 base damage (and this is the only damage that matters for the sheen/trinity force) at 18 that would only be an added 150 with trinity force which you could have just gotten another bloodthirster for the 100 damage and lifesteal. but i do agree with the ad sheen(not the alternative one though) its one of the few items to give magic resist, cant take that away.
