I have a small question regarding damage.

Ok so i also have question regarding fracture.

I am newbie who Tank dungeons as a Warrior and even i don't have any problems with keeping the aggro i still use fracture on second, third mob (when they come in packs) to do some damage and keep the aggro when i fight the 1st mob.

So the question is : Is it worth to dot other mobs or its still a TP waste ?

As was pointed out it is a dps increase but you need to get the full duration out of it. Your example is the correct way of using it. If you use it on the primary target it will probably die before the duration of the dot is up which makes it a waste.
