Had a couple of fun games as silencer. I'm terrible in the early game, but quickly pick up the pace once I start getting the kill assists.
Not sure on my item build though, generally get the scepter for the global ulti damage and mana drain, as well as a scyth for the control and a dagon 5 for the int boost and to have a direct damage spell to burst off.
Also had a great game with zeus, doing to tried and tested pubbie build of thundergods wrath + refresher. Its just so much fun, and works really well psycologically since the enemy team suddenly know I can deal 1000+ damage to all of them instantly.
Finally, I need to start buying more items that actually require activation rather than simply being passive. How do you all have your item binds set up? I have two on my mouse side buttons, one on space, and then the others are just c, v & b, but these are so awkward to hit that I never end up using any items bound do them... but I don't know what other keys would be easier.
