Lack of LB

[sheepysheepy]

makes sense to use it asap unless its actually needed for a certain moment

lb3 followed by lb1 gotta be better than sitting on a lb3 for 2 minutes

most fights you'll be wanting to use it to make things easier at some point, but if its purely dps.. don't sit on stuff

Or if your high enough dps boss is dead before bar is even filled
But i do agree lb just makes the fight quicker and why not use it.
Now the timing on many mellee dps on the other hand, well not many know the correct time to use lb i have noticed.
