clarity, no defensive item, starting with vampiric scepter = no survability early game, and neither late, oh god

Didn't read very far into your build, since you're still working on it, but I suggest altering your item build.

Boots of Mobility are much more beneficial than Berserker Greaves, Last whisper isn't very beneficial either unless the other team is all building defensive armor items. And the bloodthirster is kind of hit or miss. Lifesteal doesn't do much for Twitch, and you can probably get more from another item once thats figured out.

Good luck!

Sounds like a plan, Thx!

Make a list of what people might be doing wrong and provide solutions...that would be much better ;)
