Returning player, are there low level folks to group with?

[Rimitto]

There are a few lowbies here and there, but most of them are probably alts.
most people that use alts though are generally twinked to all hell and don't stay small long... they know all the secret fast leveling places.

enjoy the game as you can and as you will.. most of the people you see or don't see will depend on what time of day you play, rather than what level you are.
You'll see far more during the mid day and afternoons in america-time than you would in korea-time.
