Either way you ask can backfire. I remember one time doing Aery when leveling my BLM with a friend(IIRC he was WHM). The tank(PLD) was using only Provoke to initiate all pulls, he was using Flash and his rotations properly, but only Provoke to get the first of the mobs attention. When my friend asked why he preferred to use Provoke over Shield Lob(didn't say anything about using Shield Lob being better than Provoke, just why he preferred one over the other), he basically lost his shit and refused to move any further into the dungeon(we were right before the second boss). Even the PLDs friend, who was in there and stayed after we kicked the PLD, said that he can be difficult but it generally a nice guy. We finished the run with no problem after getting a replacement tank.
So even questions regarding why someone prefers one thing over another can set people off...which is one reason I tend to stay quiet in parties unless people REALLY need the advice/input that I can give.
