I didn't think anything of it at first, but leveling up a tank gave me more of an insight into the pre-60 dungeons and how players go about clearing them now after the giant wave of players looking for end-game content. Not only do I constantly get players who don't understand core mechanics, but an increasing number of them claim that they've done the dungeon X number of times as if they know everything there is to know about the dungeon. This leads me to believe that either:

A) these players are purposely ignoring the core mechanics (I'm talking about things that can wipe a group) or...
B) they've been carried the number of times that they're claiming because there's an influx of level synced players going through that content.

Both of these are obviously undesirable for everyone, as they turn what could have been a very smooth and well coordinated run into a bicker storm of "you didn't run away from me when we were chained." Is it just me encountering parties like this, or is it more than just my extremely bad luck?
