Ever since BC raid have changed, such as when raids went from 40 man down to 25 man and then in WotLk when two difficulties were added with 10 and 25 man. Later into the expansion heroic mode was added, creating 4 different levels of difficulty, but later a the release of Cata 10 and 25 man became the same difficulty, and finally LFR was added, creating a third difficulty.
We now have three difficulties: LFR, Normal and Heroic along with 2 player settings: 10 and 25. Do you think this will be changed again, such as one extra or one less difficulty and/or one extra or one less player setting?
