Is there any restriction on distance for my group members to give me -12% ?
Maybe it's not that important, but I would find it very strange if I just pick 4 guys in my group while I quest, even if the guys are not in my zone !
And if group members just need to be in my zone, but can be at any distance, it would be a very nice talent for battlegrounds.
(well in both battlegrounds and quest/farm you don't spend that much time in bear, but still...)
