So I tried these out a while ago, and I don't feel they give enough gold to warrant using them over Greater Seal of Armor.

I play supports about 50% of the time in ranked and I have a few issues...

1) No gp10 runes (no gp10 masteries is fine since building tanky), this pretty much translates that you need to get kills early on otherwise you will be behind the other support in terms of ability to provide auras and wards. Which leads me to my next rant...

2) Not buying any wards in the beginning. This is a very risky move as any jungler with any brains will see that you didn't start with wards and will camp your lane. This is pretty much easy kills if they have hard CC.

3) Not nearly as bad as 1 or 2, but leveling zenith blade second over stun. Having lower cd on stun earlier will, obviously, give you more CCs over time. Yes I know that zenith slightly immobilizes, but more often that not would be able to use a stun over another zenith.

Not a fan of sunfire or FoN (prefer abys scepter if your ap carry isn't going to build one, moar auras!) on a support, but I won't fault you for that.

Mmhhhmm.

dude, he is maxing his W, still it is not a given fact or written law, that this is the ideal/best way, it is the most popular way because this spellorder gives you some mistake-tolerance.
You can go this way, if you need the tankyness. If you are able to play without this bonusarmor and are OK with the resistances you get from your runes / masteries, you do not have to max W first and go for the CDR on the other skills, especially when you are using armor-marks, how my way to play her is.
It is NOT a written law that you only can max W first to be successfull.

But i really do not want to discuss with you in a completly unrelated guide how to level up the spells of leona.

See?He is also maximizing his W.It's a lot better than Q or E.

I miss some Aegis of the Legion, also Shurelya's Battlesong is pretty late, but would give a huge benefit to you and your teammates. Maybe think about the buildorder you suggest one more time ;)

Also: Runic Affinity is a bit wasted because you will almost never get any buffs, why not take this skillpoint and put it in Summoner's Wrath ? This way you would increase the effectiveness of your Exhaust

This is good,but can be better.You have giant armor and descent MR.Trade some armor for magic resistance.
