The problem with WoW's method of cutting off most of the dungeons at max level, is that those low level dungeons are then hardly run.

If the goal of someone running the roulette is to farm the rewards for completing it, wouldn't a stricter iLvl sync be fine if the quantity of the rewards for said roulette were increased as well (since the dungeon would be harder)?

For those who want to be able to trash the dungeon because they want their hard work to show, I thought that was the point of the high end-game content? The entry level-50 content is filled with ... entry level-50 players. Many entry level-50 players actually want to experience the dungeon when they run it, because that's the kind of environment they're use to from dungeons pre lvl50. In the pre-lvl50 dungeons, groups aren't pulled 5 at a time (that would cause a wipe easily).

I believe playing a dungeon in the roulette should be at least a fraction of a challenge, you're getting a reward for it right? A group speed-running through a dungeon involves pulling half the dungeon, aoe'ing them down, burning down boss (avoiding 75% of the mechanics due to excess dps), then repeat. That isn't a challenge, that's a loading bar.
