This is a guide for Caitlyn in the brand new Season 4. With lots of changes, mostly for the support and jungle roles, there are pretty cool stuff you can do. This is my first guide so i hope it meets your standards
After you've got that IE or BT know you have great possibilities to get some kills, just remember to stay ALWAYS in position. POSITION is key with Cait. With the Phantom Dancer your Crits will go to the skies and deal great amounts of damage.
After the build is finish you can basicly kill anybody just remember, POSITION is always key.
Stay behind the tanks and bruisers and make all the damage possible and finish them off with your Ult. Always if you have a high priority target without the danger of getting killed, go for it Cait will make almost always 2 hits before they hit you once because of her massive range.
