If some people as suggested above actually seem to enjoy camping, then the items they camp for must NEVER provide an advantage over other players. The balance of power should not be given to the ratpack guilds with 200+ members or those without real lives who can sit in front of a computer for 18+ hourse.
I say reward those people with Red Yalmahas and Sunglasses with Green Lenses. These things can be uber-rare and extremely cool to look at. People can know they will probably never have a chance to get these items. This is fine.
EDIT: I saw a post earlier that mentioned the time when Katara sunglasses were rare and sold for millions. These are the kinds of things that should be rare. They really mean something to the person who has them. He/she really looks cool in town wearing them. Not everybody has them. Hence those with gazillions of credits to spend or those with true luck or leet camping skillz get to have them. I was kind of pissed when these sunglasses became commonplace. On the other side of the coin, things as unbalancing and game altering as the Blash Shirt and Shades, should be as equally available to all players as Nullity or Grid Armor is. Whoever heard of somebody 'camping Grid Armor'? Sure you hear whining and moaning about its rarity. But, you don't hear someone complaining about hogging the Gravebeau spawn. Think about it.
What must NEVER happen is that something that is actually useful and game unbalancing is put in the hands of the lucky or the campers. The prime example is the Black Shirt of Zuwadza. This item adds over four complete levels of pet creation skills to a metaphysicist. This is utterly imbalancing in favor of those who have this item. The problem is that not every player (who provides the same 12.95 to FunCom) has the same opportunity to get this item. This is the situation that is having people quit the game. This is the situation that is having me consider ending my subscription.
If I want this item, I must either join a huge guild or .... well, that's about my only option. If by some bizzare freak of human nature, the huge guilds decided to let the Average Joe have a shot at this item, then I would have to sit for 18 hours and 40 minutes next to 96 other players waiting for him to 'pop'. And then have a 1 in 20 chance of getting his shirt. Where's the skill in that, and more importantly, where's the 'fun' in that?
Now, the lucky person who is in the huge guild and gets 'issued' his shirt will always and forever have a better pet than me. Why is this fair? How does this make Anarchy Online a better game. Is it preferable that opportunity is not equally meted out to the players? I think not. Rare items should be fore rare item collectors they should be valued because they are rare, not because they are powerful. If an item is powerful, it should be rare ONLY because it is difficult to obtain. However, the OPPORTUNITY to obtain the item absolutely MUST be equal for every single player who pays to play the game.
Players should be competing against the game for useful items not each other. Putting me against my fellow player in a struggle for an item will have me cancel my subscription. I'm not an a-hole and refuse to engage in childish pissing contests where two children are each tugging at the toy they want to play with. You know how that ends .... one of the kids starts crying or screaming his head off while the other sits smug and waves the toy at the 'loser' to add further humiliation. This is Anarchy Online now. Only 95% of the player base are losers. That's why these boards are FULL of logical and mature players posting about how foul a situation FunCom has created.
If both kids were good and ate their meals and cleaned their rooms, then both kids should get their own toy. End of story.
