I don't think we need more GMs to make more events. GMs make events tailored to the average everyday player. What XilliX and others in this thread have pointed out is that it can only go so far. If GMs started tailoring even one event to a certain faction of player, there would be complaints (trust me, there have been in the past) that they're being biased. If they don't tailor to different factions, they're too mary-sue for alot of players.
So I suggest that rather than complain, you do as XilliX said. MAKE events. Start your own story, make a rich, deep history and cater to certain styles of player. Be creative. Make a guild that isn't just a hollow name and an extra chat tab, make it a business, a priesthood, a militia, a band of thugs, or even hunters. If you're thinking of making your own guild but see another that has this specific purpose, join them! Support guilds where hard work has been put in to make it unique, purposeful, and authentic to PlaneShift. There are many guilds, alliances, roleplays that need more support to get off the ground.
Putting in some effort and researching your character's race, giving him a well-thought out description, choosing a career, and either joining or creating a specific, goal-orientated guild that is in character to Yliakum and the world of PlaneShift is what makes the game for me. Trying to figure out whether someone is deviously tricking my character or really in need of my help, deciding whether or not to follow that suspiscious menki down the alley, running small-scale Roleplays with characters I randomly meet on the street...
...these are things you could be doing rather than writing paragraphs as long as mine about how everyone else isn't doing enough.
