I wouldn't actually mind neither the difficulty increase, nor the separate hard mode. I never minded their current state at 75 either, as many of them were lowmannable, but it's a lot harder now because no one has 75 specific gear anymore. If they made it as challenging as it was at 75, I could do quite a few of them again, I wouldn't even mind teaming up with other people who want.

The idea of a hard mode actually sounds pretty interesting, because ENMs were fun at 75, and it was unique content, unlike anything there is out anymore. I'd love to do random weekly battlefields with one or two friends of mine, even if they don't add a hard mode, they should definitely add more of them again.
