ms/os is not a valid loot rule apparently^^

blizz -> wysłany:
i always thought that if the rules were stated in a lfg group then people had to stick to them and as long as it was clearly stated in the lfg tool where you sign up then you could get redress if some one broke those rules, however it seems fine for people to roll on things they don't need in order to just trade it to some one else or try sell it.

"Thank you for taking the time to contact me today.

I am sorry to hear that this has happened to you but having looked into this I am afraid no rules were broken. MS>OS is not a valid loot rule and as such not something we help with as we cannot see what specialisation a character was in at the time. If a player was able to roll on an item them no rules were broken. Once an item is given to a player (even by mistake from a ML) then it is theirs to do with as they wish.

If a Master Looter was used for the MS>OS rule it will still count as a Master Looter rule set and as such the items are theirs to do with as they wish, it would also be up to the ML to decide if a player can roll on an item they already have.

The only loot rule where a Ninja can occur is Master Loot with some clearly stated rules, like no items reserved, or all loot rolled for, if the ML then takes an item with no roll or goes against the roll this is something we will help with, these rules do however need to stated in a public channel for the entire group to see. Again we can only help if all players are able to roll on an item and not in a MS>OS or similar situation. "

poor show blizzard, making it easy for people to just roll on everything and trade or sell it regardless of needing it or not even after ms/os was clearly stated in the lfg sign up tool

I've commented on this before, but MS>OS is an extremely vague and fluid concept. For example someone who mains a Protection Warrior might join a raid as Arms because all the tank spots are full. While Protection is technically their MS, they are in the raid as Arms, which causes other players to believe that Arms is the MS of that Warrior. Is that Warrior, or the Master Looter, then in the wrong if they receive a tank trinket?

Likewise, what about players who change specs mid-raid (such as a DPS switching to Healer) to allow the raid to continue if the group can't backfill people who have left, where do these players fit in with regards to MS>OS?

Let's then say that the raid leader fails to update their LFG listing to reflect the change. The change doesn't get explained to the DPS who subsequently join, causing them to feel that something has been ninja'ed when the now-Healer is given a DPS item. Is anyone actually in the wrong here?

These are just some examples of the ambiguity MS>OS can fall into.

Generally, the Master Looter system is intended to be used in groups of people you trust. By joining a PuG raid with Master Looter set, you join knowing that the Master Looter has the power to assign the loot. If you don't seek precise clarification, in chat, on how the loot will be allocated, our Game Masters cannot then assist you on the basis of unspoken assumptions when so many grey areas are in play.
