agreed, with bane i can rape pretty much anyone 1v1 and end the game before they become dangerous

Vladi with Troll... a serious Fail!

go for Helm of Dominator as LL Item, it gives your range LL too and also allows you to dominate creeps which can be very helpful with Troll.

Also Skadi is a Fail... You dont need slow, you have Stun.

Go for:
Power threads
Helm of Dominator
some Wraithbands
Butterfly

Butterfly is the best Option you have with Troll High Dmg, High Attack Speed (stuns more often) and Evasion.

A vlads with troll isn't always a bad thing. Later game the only time you should really go ranged is to hit someone running.

There is cookie cutter item builds for chars but a lot of times your item builds and what order you get them in even is going to vary greatly on game type, if it was 5v5 or 3v3 or w/e, and who you are against.
Bracers/wraithbands are good if you are going against people that like to harass but sometimes you don't really need to spend the gold on them if you can farm easy early game.

I would say go: Treads
Helm of dom/Satanic
Bfly
MKB
Buriza
Vlads/AC (depending on playstyle and need)

it's fun getting bashers for ranged and stun/owning

or melee....get a ton of +str and watch the bashes come
