Blood Warder (12v12)

This build rocked for 12v12 since it helps your team out for defending and provides great offense to pack an AOE punch.

Attributes:
8 Blood
16 Earth
11 Energy

Skills:
1.) Well of Blood
2.) Ward of Melee
3.) Eruption
4.) Stone Daggers
5.) Blood Renewal
6.) Armor of Earth
7.) Earth Attunement
8.) Elemental Attunement {E}

First off before you do anything prior to battle, make sure you get both Attunements up. Basically go with the larger group of the team to capture vital bases and help defend with Ward of Melee, and keep yourself alive with Armor of Earth and Blood Renewal. You should be fine since most people are melee based anyways. Cast Eruption at a large group, especially if there are alot of minions around and Stone Daggers to provide some spam relief damage. Lastly, if anyone dies, throw up Well of Bloods to help heal your team and keep throwing up Wards.

Nice build, its kinda like my WWF (Well and Ward Factory ) build for UW/FoW.
