Finally broke the 340 mark on my feral bear and that seems to be the magic number for turning normal instances from the careful pulling, CCing and making sure the healer drinks every pull to something pretty much resembling a relatively quick and painless instance run, even with a substandard group (no clue what other classes need to reach the same comfort zone though).
On the other hand, that's certainly not the right level to even think about the easier heroic instances without at least an equally well equipped (and competent) healer - Blizz wasn't playing games when they designed this xpac and I foresee a long journey to heroics being casual runs for me at least.
That said though, this isn't a QQ for Blizz to nerf the instances - I hope they leave them just as they are as that means that I get more time before the heroics turn into a simple "lets get this out of the way so I can get my daily reward and go do something challenging/fun" routine.
I like the fact that I'm getting my money's worth out of this xpac as I must admit that I was rather worried that it would degenerate into an alt fest fast (and a very short one at that when one takes into account how much bonus xp gear is out there) considering how quick and easy leveling was even without the bonus xp gear working post 80. With heroics being on par with the last xpac's 10m runs this means that not only do I get a lot of mileage out of them with my main, but my alts will enjoy a long uphill journey through them as well.
My guild's taken a few tentative stabs at the 10m raids but isn't even thinking about 25s at the moment due to how rough the heroics can be - heck, many of the heroic bosses have the health and fight times of a Wrath raid boss so I can just imagine how lethal a battle with a real 25m boss will be (yeah, I popped my CD three times that fight - isn't your CD on a 10m timer - yup).
Can't end with rant/QQ off because I'm actually quite happy with how rough it is - my gal's working this Saturday and I've got no pressing matters to attend to so I'm looking forward to a long, rough day of getting to know the routes from the GYs to the heroics a lot better and maybe even scoring some upgrades - happy wiping!
