Xirus, I played about 10-12 games with your build today and lost two, maybe three. It's much more fun for me than AP style.
A note on ghost, though. If you're solo-queuing, I think that ghost can be a good idea. The only games I lost today were when my team was absolutely uncoordinated: people going off on their own, weak carries thinking they could take on three champions, nobody looking out for stealthers, etc. In these situations, it's harder to just "know" where all of the enemy team is. I agree that with good map awareness often you can do pretty well, but with chaos group tactics, oftentimes you can be caught unawares after not even sitting in one place for the 30 seconds between gates. In these kinds of games (that happen maybe 30% of the time in solo-queues), ghost is great as an escape mechanism, or to just get some distance up before you gate out. 14 seconds of 34% increased move speed on a very, very short cooldown - especially when compared to rally - has its merits.
But all-in-all, I'm really enjoying the build that's been developed by you and the guide responders. Cheers, and here's hoping that TF doesn't get nerfed any time soon...
