Hijacking the thread to ask a few questions myself:

Is it ninjaing if you state at the beginning of the dungeon that your main spec is different and you just need for that (common practice in VOA, yet idk about RDF)?

Can you need for transmog if everyone else greeds?


Why the hell if it common practice on this server that there is no pvp main or offspec and you can roll for everything? Its BiS pvp gear and garbage pve gear, yet the pve gear is treated "better".
1. a) RDF MS change: I think it is considered ninja. You can always ask and if they (all) agree on your MS change, take a screenshot of them agreeing and roll for your new MS.
I've heard something of sorts: what you join in as is your MS in RDF.
b) Raid MS change: Whatever MS changes are in raids, are up to RL/ML.
2. Xmog is Greed roll, as I said in this thread before: "Greed = Everything else. Vendor, AH, OS, Xmog."
3. It would be too hard to know who has what PvP spec. Since all PvE raids are done with PvE gear, PvP gets treated as a secondary.
