Why the separate lockout? So 25mans would have an option of running a 10man IF they don't get enough raiders? That can only cause problems. 10guilds going apeshit because they can't raid 25 to have same gear, 25man guilds would probably have problems and drama with other 15-20 people being benched because "the skilled" group is farming gear.
They should keep the shared lockout, problem solved.
I disagree with the argument that they are gating content for KR because they are too HC for this. A simple look at Wowprogress proves that they are not burning trough the content. Also, the very top west guilds do in fact play 10-12-14h a day. Don't know why you think that they don't.

Maybe they are experimenting what the general feedback will be. Granted, they did not do it ever before but also 25mans weren't in such a bad position until. They obviously need new tools on how to revive 25man scene.
It is the start of the expansion but according to numbers there a 2500 25mans out there that killed 1st boss in MSV which is just laughable at 60 000 25mans that killed Marrowgar. Yes there are 2 million less players but that is a very steep and large decline. DS FL had 5000 guilds killing 1st boss. Even that is pretty low. I don't see that number doubling at the end of this tier. From personal experience, I know a lot, and i mean a lot of people in 10s that would rather raid 25 but 10 is just more convenient, not preffered mind you, just less troubling.
Personally I raid 25mans, I've always preffered them and I will probably quit before joining a 10man. I don't hate 10man or anything, I just couldn't raid in an environment that doesn't feel massive and epic. A lot of other players that I've spoken to have similar thoughts on the subject.
I think this is the wrong way of reviving 25s. Ilvl advantage is too high and separate lockouts will cause nothing but drama and quitting.
