Intoduction & Conclusion
This isn't a guide to caitlyn, its a simple build, give it a go, and have a rate im just doing this to share a great build that i have put together after looking at a bunch of others. Screenshot proves it is a decent build but give it a go. Also the last few items should normally be interchanged with others, depending on the other team.
