You're free to give your opinion here mate
We got different rules in our turf!

Anyway, I would say there's a fairly good chance blizzard will make the next pve content WAY harder, or at least quite a bit. There have been a ton of posts on the forums saying wotlk "is too easy" and stuff like that.
Several threads on the main pages...
I personally hope they will make it harder. It will put not just me, but the team I currently raid with to the test.
We did Instructor Razuvious in like 3 tries, mainly because 3 of our 4 priests are new in the guild and we did 2 wipes solely with the mind controlling so they can learn it without having the spells all over the boss

Also, four horseman same thing tooks us a couple of tries ,but it's so easy :/. Just facerolling.
My guilds first time in naxx10 they cleared the whole place first time in 3 hours 30 minutes ...
