Question about building a tanker fighter

[Hyper]

Hey, sorry for hijacking this thread, but I have a question to ask @__@"

I've read somewhere that mock doesn't actually generate aggro, it just brings a fighter's aggro level higher than the highest amount of aggro generated within the party.

Is that true?
So, whenever aggro is lost, the fighter can just mock again and bring his/her aggro level higher up than the person who took aggro.

Not true.

Im not sure, but if it was true, wouldnt the dds get the aggro if they attack after mock?

like for instance, if aggro could be measured by a number, and maybe a mage has 50 aggro towards a monster, the fighter uses mock and now has 51 aggro towards that monster, then when the mage attacks again and recieves 20 aggro, bringing the total aggro to 70, then mock would be useless right?

There aren't levels of aggro...

If you use Mock [2] and continue to attack a mob, it will take a long time for a mage to steal aggro. They really only steal aggro a lot with lower leveled taunts and if you don't attack.
