You really shouldn't publish an incomplete guide :/ You'll just get a lot of downvotes.

To the guide:

• 0/16/14, 0/21/9, 0/9/21 Mastery is better.
• Your guide has very less information though, some chapters that are important: Items, Gameplay, Warding etc. are not in your guide.
• You have no Ruby Sightstone/ Sightstone in your Full Build.
• You should do some codings in your guide.
• Your runes are totally wrong except the Glyphs,
  Marks: greater mark of hybrid penetration, Greater Mark of Magic Penetration, Greater Mark of Armor, Greater Mark of Attack Damage
  Seal: Greater Seal of Health, Greater Seal of Armor(I know you got it there already but as gets a buff and gets a nerf, it's more wise to choose Health Seals.
  Quintessence: Greater Quintessence of Armor, Greater Quintessence of Health.
• Ruby Crystal and Doran's Shield start is also mentionable.
• Warmog's Armor is not a good support items, it is more a selfish item, you should change it with Ruby Sightstone at Full Build.
• Change Stealth Ward to Sweeping Lens after you got Sightstone since you don't really need the totem anymore.
  
  
  Conclusion:
  
  Your need to change most/everything on your guide, I suggest you to archive it and finish it before you republish.
  
  Good Luck ^^

If it's not finished, even more reason to downvote.

Why would you submit a piece of work that's not finished yet? That's just asking for trouble.

Besides, an unfinished guide doesn't explain your poor runes and item choices. You can't BS your way out of that one, unfortunately. The fact that it's under construction does not mitigate the fact that WHAT YOU HAVE is bad.

Hello and thanks for giving a reply but you got to understand i have not finished this yet. It is far from finished and maybe shouldnt even been released at this point i understand taht. As this is my first guide it will take some time before it will be finished as I have a limited amount of time on my spare time. However the strong criticism is harsh when you dont even bother readon the HEADLINE where it say it is still UNDER CONSTRUCTION! Maybe you will change your minds once it is done. I dunno. But as I said nothing is really finished yet. So sorry if this was a dissapointed so far.

You don't mention upgrading Relic Shield to the final upgrade and I guess many of your situational items which are not supportish like Spirit Visage and Warmog's Armor in your example build are questionable choices. 0/21/9 seems to be a better Mastery Tree and on Leona I'd rather say Fleet of Foot > Meditation .
Ignite is your standard summoner spell and you should probably mention Trinkets more in the cheat sheet along with the Trinket change after purchasing Sightstone ...

Well, I opened up your guide and saw Exhaust as the suggested spell and that actually put me on a sour note for the rest of the guide.

And I was not disappointed at all.

I question your runes, I question your items and your masteries.

Then the guide is lacking in pretty much any meaningful information.
