Building Limit Break

[Lollie]

You may be miss interpreting the statements that are separate from each other. The below are all individual items.
When engaged the lb always fills at a consistent rate depending on how many party buffs you have.
Any damage mitigation or returning status above critical generates roughly5% assuming you don't die in the process of a lb bar (parry, block, heal)
Any interruption of enemy abilities not caused by los generates roughly 5% of a lb bar (ie stunning eruption, silencing high voltage)

I'm sure there are a few others as well. The reason why its not done usually is because unless you have to have the lb at a specific point it is as stated its risky and if done wrong is a net dps loss. Assuming you do 25k dmg with an lb3 each event giving 1.66% of all 3 bars you get a flat gain of 415 dmg an event. If the person dies it takes roughly 8 sec (being generous) to get them up to speed again. So you need to get 4 events in to make up the difference in dps loss if the tank is pulling 200, not factoring in the loss of any healer gcds used to get them back up, and any tactical disadvantages.
