Dont you hate it when you leave a group/raid and all the nice buffs disappear? Me too. Then I found this trick.
- Have some buffs
- Dont leave the group
- Log out (some places throw you out of the group, some dont. couldnt figure out which and which dont)
- Log back in
At this point you should be out of the group/raid and still have the buffs. Hope it helps.
