How Often Do You Use Tank Limit Break?

[Paikis]

The only time you can justify using it is before pulling a boss when you have a full bar and the bar gets emptied when you pull.

Other than that, it is never worth using.

Honestly it should be worth using more. Something like:

Rank 1: Tank receives no damage from the next attack.
Rank 2: Tank receives no damage from the next 5 attacks and each party member receives no damage from the next attack against them.
Rank 3: Party is immune to all damage for 10 seconds.

I almost suggested something to do with agro, but honestly I dont tihnk I want the ability to grab agro on all targets engaged or something like that. You don't always want to be tanking everything.

This. Sir can i give you a cookie. How about a model of your choosing? xD

Or at least something along the lines of:
Rank 1: greatly increases Phys/Mag Defense. Something like 20 - 30% for 10 seconds
Rank 2: greatly increases Phys/Mag Defense. Something like 30 - 45% for 10 seconds (Or maybe even something like Scholar's AOE defense thingie)
Rank 3: Party-wide Hallowed Grounds

Especially since the current LB's for tanks is just like casting a party wide Rampart... before the Trait buff -_-
