ok so iv been playing caitlyn for a long time and iv always gone zeal-->bt-->phantom and recently iv heard people saying that its better to finish the zeal first and iv done it a few time but wasnt really sure if i liked it more or less. pls comment what you think

I prefer BT before zeal due to AD scaling skills.

1/2 Dorans > Berserkers > Vamp/ BF > BF/Vamp > BT > Zeal > Phantom > Infinity or Last Whisper. > Banshee's/GA .

If im dominating in cs and have some early kills i almost always rush IE. It works for me, but after as boots i would BT before zeal just to max it faster.

NEVER buy zeal before any damage items. What's the point of attacking faster if attacks don't do enough damage. Especially early game when your main focus is CS. Damage makes it easier to CS and if you attack faster you push the lane easily.

i think some of you may misunderstand. I dont start my build with this. In a game when i am getting average cs/kills/assists i usually go...
dorans-->boots of speed-->dorans-->berzerkers-->bf/vampiric-->bf/vampiric-->ie-->zeal-->bt-->phantom-->banshee's/last whisper-->banshee's/last whisper

so my question is after getting ie, what do you think about going zeal-->bt-->phantom

Oh and finish thirster before you buy zeal. The sooner you can max out the stacks the better.
