I've been playing WoW for less than 1 year and only now have been reaching end game for the first time. Let me say that I have no idea what an unbuffed ICC looks like, but I know for sure that if I could learn the strategy and execute it even just sufficiently well, anyone can. I think dedication, experience and patience should be rewarded and I'm most often than not feeling just like that in Loardaeron ICC experience. I pug a lot so I know what it feels to 3-boss ICC all the damn weeks. All I wanna say is that, as a gamer, I'm satisfied with the Loarderon vision, but I'm not satisfied with the current state of the raiding experience. I'm sure my pugs fail because there are people who are not up to the challenge: they are not prepared, they underestimate the raid, fail at skill checks, refuse to put up with any tactic that involves pressing any button which is not in their preferred rotation, they slack and don't invest time nor gold in their characters. On the other hand, I'm also sure at least some of those fails can't be accounted on human error, but merely on hard numbers. Therefore I'm joining the choir: I want a challenge, not a lost cause.
If I had to quantify the tuning I wish to see for ICC, I'd say that it has to be around 15-20% easier than it is now. The reason is that top guilds of selected individuals are those supposed to see an end game raid as a moderate challenge and therefore can't be the standard to gauge the difficulty. Ideally, the top 10% of the server should be able to clear ICC 25hc with moderate effort and the 10% below should be putting some real effort into successfully doing it, with the average players being able to at least see their *** handed by Putricide/Blood Queen on a weekly basis and stuck at, let's say, DBS on HC.
