Sorry, but raid content shouldn't be the "very easy" mode equivalent.
It...isn't? LFR is. LFR exists so that people have a chance to see it with minimal commitment. That's not 'raiding' by any sense that anyone actually uses, so why get butthurt over it? Queueing makes people do things they wouldn't do, the convenience of it. Queueing is also GARBAGE if mechanics are the slightest bit challenging. Ergo, anything you can queue for, even a 'raid', needs to be easy.
Wait I can invite other people in other realms to do dungeons and raids with? Wtf?
You can even quest with them out in the world now
GW2 and other games make transferring easy or let you 'guest' or whatever other technology, meanwhile blizz just casually rolls out complete cross-server play with no load times (you just phase in and out and are on a different server). GG. It's very slick tech. I expect to see the AH go regionwide at some point too, making low population realms even more viable as time goes on.
