COme on guys....there is ZERO debate here.

Go look at the top raid guilds in the world and look at their MT's. ALL...I repeat ALL have a fast weapon.

No one who has ever tanked anything Heroic or above would even argue this.

As for asking the question. That is what a forum is for.

IMHO

The sun eater, best pré raid tankweapon, speed, 1.6
Kings defender, tankweapon from Kara    speed, 1.6
Mallet of the tides from SSC tier5 region speed 1.7
Unbreakeble wil from MH                  speed 1.6
The brutalizer, best tankweapon pré-SWP speed 1.6
Tank weapon from SWP of wich im to lazy totype the name, speed 1.5

Any more idiots that wanne argue?
