1. IF you were actually grouped with a "raider" and IF he actually wanted the item you claim to have won, it is highly unlikely the "raider" will care that you won. Most, if not all, "raiders" are well aware that any item they desire will be available to them in short order.

2. IF you were actually grouped with a "raider" and IF he actually wanted the item you claim to have won, and IF you expressed your idea for "revenge" on "raiders", rest assured you will, undoubtedly, no longer be welcomed by said "raider" or his "raiding" guild or, for that matter, in any other "raiding" guild in future.

3. IF you were actually grouped with a "raider" and IF he actually wanted the item you claim to have won, and IF your behavior in game is anything at all like your behavior on these and other boards (where you posted this exact same message), rest assured you will, undoubtedly, no longer be welcomed in most groups let alone raids on your server. People do have a way of communicating about such behavior.

4. IF you were actually grouped with a "raider" and IF he actually wanted the item you claim to have won, and IF you actually think "raiders" are in some way "dependent" on "groupers" for anything other than pleasant gaming companions, you can rest assured YOUR suggestion to "withhold" buffs and to "withhold" help will have "raiders" falling on the floor in fits of hysterical laughter.

Enjoy your winnings.

Oh, you certainly don't seem the least bit interested in knowing that "raiders" had very little if anything to do with the changes ongoing and upcoming to the "Classic Monster Mission" events and to the gear, but that it was, in fact, those who play the "group" game who first brought the inequities of the gear to the attention of the Developers.
