Show me the parse please then, because I see no significant damage from it. Gathering mats, does not pertain to OPs/FPs/Heroics in this instance. The thread is purely pointed to the pet. I can gather resources -anywhere- So can any other gathering skill. So yes, that skill, until the parse shows some -amazing- dps for it, is not useful. You can gather mats anywhere, it does not provide anything to the group besides a pet that, and I stress -might- do minute damage. Even while leveling the damage wasn't noticeable, let alone in a 55 hm.
So yes, it is of no use. Also, I think I'd kick a member for gathering mats in a FP, unless they asked and we all agreed. It's so slow, I'd rather get my run over with.
You sound like the type of person I would kick out of my FP's and be sure to tell people not to group with as much of an unpleasant person you seem like, point of the matter is that Bioanalysis is not worthless, you're only mad because it doesn't let you take advantage of what was clearly a glitch.
Also I've seen that pet critting for 2K and doing normal hits of close to 1K, that isn't something to sneeze at.
