Side note: the greeters dont go out and bother the fr00bs to the game..so lack of seeing them isnt becasue they are overworked from working on fr00bs.
Allthough something to note...greeters dont stay as a greeter terribbly long. typically after a short time..you either wash out.or you have promise..and you get bumped up in the hierchy. You still need to greet..but its not as hardcore..nor ..well frankly nor is is something anyone gets paid (all greeters are voulunteers anyways...to my knowledge...nearly no greeters are funcom employees..tey are managed by such.but anyone youd see appear is someon with some scripts who is trying to help.
Based on that, and the current....fluxuation of people who powerlevel, speak leet speak..and generally rude...might be the laxity upon seeing few greeters anymore.
