I know a lot of theorycraft have been done around the 40man to 25man and 10man raid move, Blizzard claimed that one of the main point was to add more utility to hybrids-classes/template.
Of course only the future will tell, but i found this video :
So what does this video show, it's an Karazhan video(10man raid instance), recorded by an Elemental|Dps spec draenei shaman and their main-tank is a protection spec Paladin ! quite funny specialy since it look like they are doing good.
Sorry for the video quality tho.
Feel free to post your hybrid's video exploit in comment !
