Just wanted to set the record straight for those who aren't quite aware of it.
Ninja Looting: Blizzard's Stance
Have a nice day. :)
Thanks! I was getting ready to link that in that other thread, but it capped before I could.
I think it's important to note that our support policies match what's reasonably enforceable, and this really can't be a conversation about our support team making the right or wrong decisions, or helping or not helping. It's unreasonable for them to act as arbiters for every piece of loot that drops in every dungeon for every player. I hope that's something we can all agree with.
What can and should be discussed, and something we've been discussing a bit more internally, is the loot rules themselves to potentially prevent the issue in the first place. Clearly the current dungeon loot rules are fairly lax to allow for people to gear up in different ways. We (at least currently) want people to be able to gear up to tank by DPSing, or being able to help out others by healing when they really just want to DPS in their weekly raid. We want to allow them to run dungeons over and over to make up for bad luck in their drops. Just with those two things combined there will be people in your groups rolling on items you believe to be better for you.
One side issue that's made this all seem much worse is that with the launch of Mists a lot of items were tagged incorrectly, leading to people being able to roll on items they just have no business being able to roll on regardless of specs available to them. That makes the system just seem broken, when it's only a couple items that are essentially 'bugged'. We of course want to get to those bugs as quickly as possible.
There are clear benefits to allowing people to roll on off-spec items, or run dungeons over and over to try to get an item (or even just because they enjoy dungeons!). There are also clear issues it can cause when the factor of who 'deserves an item more' comes into it. Being matched with strangers you can never truly know someone else's intentions, and conclusions are easy to jump to. The converse though, where you can only roll on your current spec, is a system where you're locked into gearing up a specific way, and discourages (or maybe completely blocks) changing roles or even gearing up an off-spec - even if no one else wants an item.
There are many considerations to be made, but the discussion of LFD vs LFR loot systems is a larger one than even just this issue, and the devs seem intent on discussing it more and more as this expansion rolls on.
Until then, if you want to ensure you get the drop you want, I really recommend forming a group with trusted friends and guild mates if at all possible. Plus you can talk trash on them the whole time, which makes everything with friends more fun! ;)
