Finally hit level 50....but I read too many horror stories on here that I'm scared to start any level 50 content, and intimidated. Everyone in revenant toll is glowing in high armor aura.

What should I do first? Just grind the level 50 dungeons (Meridianum, Praetorium, Wanderer palace) to collect Mythology for my Allagan set pieces?

Are these places OK to enter with level 50 gear AF? Any other suggestions how and where to start?
