Best place to lfg at lvl 20-30?

Hi all,

I am finally over lvl 20, where is the best place at that lvl to look for a raid group?

Dion?

I always found Gludin very useful. Dion is also pretty good though.

I would say Dion is your best choice, Gludio is ok too but not too many people there.
Dion is where my low lvl alts find raids.
