you are getting 2-3 raids this tier and you can still do 25's, you just want to force people to do things they don't want to just for the sake of gear, people will always try and get ahead by way of the least resistance. I don't see why a 25 man raid needs better gear to get people to do it, people need to do it because that's what they want to do and if all people who say they want to keep doing 25's do so there should be no shortage of 25 mans
I don't mind blizz making tougher raids and not nerfing them but then they should also provide easier raids which provide rewards for the less driven people , and what happens then is that the "hardcore" will also farm this content if it gets them ahead and complain they have too much to do while the others will be sadenned that there is content they can't do due to the difficulty, you can say what you want, ask what you want, you will never ever get 10 milion people happy with the direction the game takes, the only downside you have atm is that it's going in a way you don't like but hopefully for blizz the majority will like.
In an ideal world blizz would be able to cater to everyones tastes and needs (up to a point) but as it stands this does not seem possible and ass such blizz is using the assets they have to provide content useable to by as many people as possible. Naxx in vanilla was nice if you want, but I don't even know if any guild on my realm cleared the place, sure it was hard but also mostly unused same for most of the last raids in tbc they were supposedly all super awesome yet only 2-3 guild on my realm actually cleared sunwell and not many more BT or MH making a game that is hard for the 0.1% awesome players might be nice for those 0.1% but it's a complete waste for the 99.9% other players who also have a right to content and if you make something for them you also need rewards for them (which do not need to be on par with the raids, but still need to be better then the intial hc dungeon blues.)
I know LFR is kinda easy yet I have seen more then 1 raid fail on bosses to the point the raid fell apart due to incompetence of the tanks/healers or even dps recuirements that were not met as sad as that may be.
