actually not a bad build... but you made it sound terrible with the following things: i haven't tried it in pvp, only vs bots and saying i'm not level 30 without saying what level you are. you could be level 2, for all i know, and played 3 games like this. i doubt that, however, bad idea. all of the guides here are intended for pvp and must be used there effectively to get some love. FYI, turret damage doesn't spell vamp for you, the pesereverance and Expanded Mind masteries suck, Meditation is way better than Greed unless you're a total support/ Shen type tank. if you're going ap, Archangel's Staff is much better for you than a Chalice of Harmony

markwise i'd go for magic pen not ap, since it will make much more of a difference, and i would go for mp5 seals not ap for the same reason.
