And the only reason 10 man had to be pushed was because a vocal minority of elitist 10 man raiders did not feel appreciated enough.
And the current model is more like
family and friends casual players-- LFR
medicore raiders-- normal raiding
hardcore raiders-- heroic raiding
Casual and family and friends are more or less excluded from the fun social interaction of normal raiding.
And sure i know there are some very good casual players but there are also a lot of not so good players in that segment. Whose skill level was good enough for normal raiding in wrath but are now damned to do lfr.
Personally i probably schouldn't care because i am sitting pretty in my own raiding guild but maybe blizz schould care.
I do remember a post earlier in this thread where someone had posted numbers of the decline of the amount of people doing normal raiding from wrath to now.
And i think that a lot of those good old customers simply can't get into normal raiding anymore.
