i like your build but i would switch zerkers greaves with merc treads. this gives you the MR your lacking and the tenacity you need to survive. other than that i find your build fine. +1
check out my build.

you have no magic res on your "Off Tank" Pantheon and with his shield most AD champs do lot less dmg then normal on hit champs very less so his naturly weaker to magic champs. not a down vote but sertinly not a + 1 good presentation tho

Oh there's definitely changes to be done. The guide is super small, and you need more facts. There's no gameplay section or any other aspects of the game besides Items that you included.

Use this guide to tell you all you need to know about making a guide.
Making A Guide
Read it to the end.

Regarding your second build, never rush Madred's Bloodrazor, it's a huge waste to buy so early and very expensive. Last Whisper is much more useful on Pantheon, so use that instead of Black Cleaver.

1.Berseker greaves should be merc treads since having some tenacity is better

2. Runes should be

Marks: Armor pen
Seal: Flat armor
Quint: Flat Ad
Glyph: Mr

3. Items warmog cost a lot and just give and only give you life I would rather go with some Mr items like Bv and finally two bloodthirster is too much (not sure If I would even pick one)

4. Summoner spell: exhaust and ignite is too much its one or another you need to have flash or you will have any escape mechanism

5. Finally you seem to like a lot As Panth and I dont think its a good choice compare to off tank panth or even ad Panth


But its always good to see someone who likes to play this Spartan and so I'll vote you up dont give up!

anybody think anything is wrong?? I will try changes and maybe put in guide depending on if they work
