I thought that the beginning dungeons were blocked off until you completed them. At least that's how the story ones are

Seriously, all but a couple are, you DO have to do them in order besides the optional ones. Pretty strange to call players bad when unaware of this fact. O_o

About the Doom tiles, one run in there, had leader telling new players the wrong thing to do when, and another i had movement problems where i would lock on to a mob making it hard to run (was on PC, but it kept doing that lock on thing the ps3 does).

Sorry for not being precise on this one.
For Maelstrom GC hunting log I had to go to Halatali and Qarn, so I was referring to optional dungeons.

What's required to unlock an optional dungeon, beside the appropriate level?
