Because Iltat is on what may be an indeffinate leave of absence, and not many of us have the experience to fill his shoes, I'm going to Post a Link to a Website that has recordings of all types of AT Builds.
EliteGamers, a player run Wiki containing numerous Build Types for every AT currently in-game, as well as some Guides that are pretty handy to have. They don't have every single type of build out there, this is just some listings based on the Personal Experience of those who suggested them to the Webmaster (Lazoris).
If anyone has Ideas or has tested Builds that they found to be excellent, feel free to direct an Email to Lazoris at webmaster@elitegamers.us informing him of them. I'm not exactly sure on his "qualifications" of what does or doesn't make it into the Listings, but I'm fairly certain that if the suggested Build holds good stat numbers and doesn't require one to have a Billion Inf to obtain, it should be reasonable to believe that it should make it to the Listing.
Note: This isn't exactly a place to go and Post requests such as we have done here, you can only Browse what's already in place there, make suggestions for possible improvements of those said Builds, give your feedback for creating new Builds, or even Post a Build you believe to be valuable. Therefore, it's not an exact replacement for what Iltat has offered for us in the Past, but in light of his absence, it's the best we know of to offer a similar service.
Try it out!
