So basically normal modes?
The problem with just using normal modes directly is that they're designed with the assumption that a certain level of communication is directly available during the raid, which isn't really doable with a randomly-created group. I think it would need *some* tweaking. That sort of thing, though.
On the subject of 5-man difficulty: One of the first times I felt I really 'got' WoW was the first time I did Shadow Labyrinth. When you don't overgear it, the bosses in there are *great*; interesting mechanics, requires tactical thought, and a legitimately cool Big Final Boss. I do recall smugly commenting with the rest of the members of the group that there were people in our guild who'd really struggle at those fights at the gear level we did them; perhaps the first time I'd really
understood the idea of skill > gear.
I'm not sure I agree, though, with the notion that normal raids should be easier than they are now. This is a tricky one to lock down, of course, but at the moment normal content is pitched damn-near perfectly at our guild. We *will* get through it over time, but we won't breeze through it. If they made normal easier, we'd coast through the normal content, and then be somewhat stuck because we're not really good enough for the current heroic design philosophy (and I agree with the points outlined about that heroic is at the sort of level it should be at; while they *could* make heroic easier to accomodate the difference, I think it'd be a bad idea.
In a sense, I think it's a flaw in progression. If you're satisfied with LFR, that's great. If you're interested in a level beyond LFR, though, it's a big leap to the next step up, and it's a leap you can't do alone. I think the solution that would work for me - although I can see many reasons Blizzard would be reluctant to do it - would be another level of raid difficulty; higher than LFR, lower than normal raids. I wonder if doing LFR-level loot but allowing it to be handed out in the normal raid fashion rather than being reliant on random rolls would be enough incentive for that.
And on the subject of normal generally being pitched at our guild: Post-nerf Horridon, we went from really struggling on the third door and often wiping on earlier ones to a raid which culminated in an extremely close 7% wipe. The fight now feels like it's at our level; barring disasters, we'll down him this week, I'm sure.
