Not a bad start. I would recomend adding some alternate runes and mastries.

i dont like this guide

Uh... i personally don't agree with Bloodthirster for ur first main item. Having a vampiric scepter is actually more than enough for Cait to be able to sustain herself. That and warding plus relying on ur gut feel. And besides, why does cait need BF first? She's range - one of the champs with the highest range. It's just a matter of positioning... this enables her to hit without being hit -___-

As carry, it's her job to finish off what needs to be finished - deal massive damage from afar. PD and IE are her first core items. I've battled against Caitlyns who used BF first and they lost against me. Why? Because my PD and IEs damage output beats BF's lifesteal. That's the same when battling trynd. So what if you have BF? If his damage is so big, ur BF won't be able to cope up with it.

Well that's ur choice. But for ranked games, i really would NEVER choose BF first. Ur team needs you to carry.

But nice for the effort. I'm not downvoting. Just putting some insights.

Happy new year!

Dorans Blades are only good if you want to start dominating your lane. Normally buying 2 is good enough to survive ganks, have a decent amount of lifesteal, and have a quick boost in damage.

And IE + PD + 2 BT is much better than 3BT + PD. If you get stunned, then whoops. You are dead before you can lifesteal. Then you have to farm it ALL BACK UP.

Also, no defensive items? A quick silver sash can easily save your life :o I don`t know, I just prefer not to go extreme glass cannon with double Blood Thirsters, because 1 death is a big chunk of your damage.

switch IE with bloddthirster, get 3 dorans blades before, this wil grant you enough lifeleech and a ****load moar damage.^^

^ Yep, what he said :)

For the rest I think you should consider buying at least 1 defensive item.

I also think Armor Seals are better than Mana Regen Seals.

And starting with Yordle Snap Trap is often better - you can place a few when you are early in lane, so you can zone your enemies.

You could include 2 sections where you explain why you took those runes and those masteries. For instance: Why did you pick the 1.5 % extra damage mastery instead of the more commonly used 3 % lifesteal mastery?

Good luck with reading the guide to making a guide, and also good luck with improving your guide :)

You should add in your guide some color and pictures. If you don't know how to make a guide then check that out:How to make a guide.
