Has anyone experienced playing LS and it feeling like no one else is on and can't find a cata gam fgor hours at end and arena by this point lvl 25 runs to slow and cata is almost only way to level.. What do you do to pass the time?

Mostly arena. If you're trying to level, what else can you do?

Other than trying arena you can try hosting your own games to get people to join. Post a thread in the Catacombs Forum seeking games for your xx lvl char or to see who else is looking and join up with them.
