When to use limit break?

Just please don't try to get the kill shot with the LB. Use it before then, so the full damage of it can be done.

Indeed - too many try to use it as the kill shot to be flashy, when it reality it is wasted dps potential due to the overkill.

I have been doing that <.<
To be fair, it's been more of me thinking "If I mess this up, nobody will care because the boss is dead" rather than any specific desire to be flashy. Thanks to everyone's kind replies, this will no longer be an issue.

I've been trying my hand at tanking; it's good to know I won't have to concern myself with tank LBs for a while yet.
