I played a game with a guy who swore up and down that homing beacon did not do damage but just allowed you to shoot through stuff. I always thought it did do damage. He backs up his claim by also claiming to have been in contact with WK.
I think you can guess what the question is.:p
So, yeah, help?

No where in the rules for Homing Beacon does it state "Do not deal damage to this unit, instead friendly units to you get +1 to their attack values for the remainder of your turn."

It would be worded like using flamers to heat up a mech if it were in fact not going to deal damage.

It does in fact deal damage & you get a bonus to your attack.

CCAF

CCAF is right. It does deal damage and lights the target up.

What is more, alleged contact with WK is not tournament-legal. The Tournament Rules state only the Rules and FAQ are legal rules references.

Clarifications only work if they actually comply with the rules as written.

Looks like you bumped into the worst kind of rules lawyer there is...

i guess it would hurt if you had something hit you so that it stuck in you after all paintball hurts and all there supposed to do is show you where hit
