I can understand why you're a bit butthurt at the fact that they won't use BOTD in their rotation, but it's how they play. If you pointed out the usefulness of it, it'd actually give them some incentive to give it a shot so they can compare. As for laziness, basically just shrug it off and move on. If they're doing VERY poorly, maybe might want to kick them for a better person(i.e. Healer only healing for 300 HP in Stone Vigil? Definite No-no). But it's DPS.

Note: As for just showing an item from Alexander...that's just some dolt saying he has completed it. Doesn't really mean anything since Gear is Gear, and IMO iLv doesn't mean anything.
