I know when to use LB, thanks

If he had to ask, that means you haven't used it and he thinks the LB bar should already be empty.

Chances are, when someone has to ask, you're already doing it wrong (or not doing it).

And why MUST we do it? To end the fight 10 seconds sooner? If it where a matter of life and death then I could see the purpose, or in fights like Levi and Titan where a mistake COULD cost the win. But, like the OP, I get tanks screaming at me to LB demon wall or Ifrit HM nails, and to which I ask why? We can kill it perfectly fine without using LB and thus saving LB for when it IS NEEDED. My argument here is based on non-raid situations and LB1. LB2 is def worth using but LB1... meh.

Do you know how many bad DPS's there are? o.O Honestly, you HAVE to tell the majority of DRGs/MNKs when to use LB as they for some reason want it to be the finishing blow :S Just use it already, there is usually no point in waiting until it kills the boss. Better have it deal more damage :P

The counter argument here is if it is used early and then the group wipes, the LB is gone.

With all the comments here (From tanks and healers, surprise) that DPS players are all so bad, I wouldn't be surprised to hear that they're doing it to you lot out of spite.

No I believe that most good DPS go unnoticed, not intentionally, but it is much easier to remember that DRG who ate every WotL than it is to remember the one who dodged everything and managed cooldowns for jumps and gaols appropriately.
