You need to take another look at your item build. No support playing at competitive levels will skip up Sightstone and Ruby Sightstone early builds. You also need to use more BBCode to spruce things up and you need to expand on your ideas much more

Ward killer 101
Leona Q

Well, I've always started Q.

^ Aha! Forgot about that ward thing. Thanks for pointing that out.

You don't seem to realize that you can kill wards with Q first easily, you can also take golems more easily. Leona cant engage at level 1, no matter what skill she starts first.

Using E at level 1 is still essentially suicide, especially for level 1 teamfights. Plus, a significant strength of Leona is her ability to zone the enemy out by brush control. Being triple-auto'd with Q is far more threatening than being E'd with no followup after.

******** Q level 1, anytime

However it is a gap closer and is more useful than a single point in Q which requires you to walk up and smack them in the face, and which could potentially cause you to take too much poke damage, making you unable to engage at level 2.

E at level 1 doesn't do ****, Q helps removing wards and works well against melee champs.

E is a root, not a stun (doesn't stop spellcasts or autos), and it puts Leona out of position (behind the target). Plus, landing an E has very little level 1 kill potential unless it's 3v2.

First skill is wrong, E is the correct start against any lane other than an opposing kill laner

Only odd thing in sequence is E at 13 and Q at 14 instead of the other way around and just maxing q by 13.
