This is my first Mobafire build that i'm putting out here. Suggestions, comments and feedback are welcome. If you thumbs down I would like to know what thoughts cross your mind

Pros to build 1:
the build 1 has a balance of Armor, health, and Magic resist.
ability to start team fights and last through them.
as well as dish out decent damage while tanking.

Cons to build 1:
2809 health may not be ideal for tanking but can easily be fixed by swapping out either Banshee's Veil for a Warmog's Armor.
early game may be a little rough but once you start getting the gear you should be fine

Pros to build 2:
Great damage output since his Bandage Toss and Curse of the Sad Mummy scales 100% off ability power, and Tantrum has a 50% scaling off Ability power also Despair scales off ability power too.
can keep up with most other champions, while slowing them with Rylai's Crystal Scepter in order to keep them at your own pace

Cons to build 2:
Although you have approximately the same health as build 1 you lose out on a lot of that armor and magic resist.

For build 1:
Teleport over flash may be considered. this will allow you to get to your team if they are in trouble, very handy for those last second saves. By using Teleport you can open up many gank opportunities by teleporting to wards, minions. towers, jack in the boxs(placed by shaco), shrooms(placed by Teemo), as well as heimerdinger's turrets.
as a tank you may want to be less dependent on your support for heals, dropping Flash for Heal is one possibility.
