how hard is it to do the simple things?

I've yet to see someone marking at lvl 50 dungeons aside from Thornmarch, i even tried marking when one of my tank classes reached lvl 50 but no one seems to bother. On the other hand in low lvl dungeons most groups i get follow the marks.

99.9% of level 50 dungeon runs, everyone is severely over-geared for the content and can aoe things very quickly with no instruction. Only when I have very new DPS do I mark anything any more in low level dungeons. It's safe to assume most party members are experienced enough to not need marks on trash.
