(Opinion of semi-casual raider.) The first boss in heroics is actually pretty challenging compared to what we've seen in DS. We actually had problems downing it second time, after we've got our first kill last week! It's nice to see that every week the fight's gonna be different a bit. I think this is gonna be a hard gate to pass through for a lot of guilds, compared to piss easy morchok. I like it. More the challenge, more the satisfaction.
