I am kinda scratching my head wondering why in the world there has to be a special set of rules for raid zones.
I understand that people want to progress, but why is the person struggling to get the Uber_staff_02 upgraded to Uber_staff_03 in the Plane of Awesomeness any more important than the guy in a lowbie dungeon trying to upgrade his mithral sword to something better? Or just getting xp?
There are really no special rules to "protect" these guys. Who has not had some group or a high level farmer swoop in and snipe the mob you been camping for hours if not days? It happens all the time and most of us have just learned to grin and bear it.
I don't raid in SOD... but I raided a lot in live game and saw the same nonsense going on there. Which is one of the 823523212879909 reasons I quit that game.
I'm not saying that there should absolutley not be any rules in place. But, lets not forget that EVERYONE playing this game wants to progress, and deserves an equal chance.
The only Real rule you should ever need is the Golden one. If you can't play by that rule then...
(b) Shut the zone down -- nobody wins! Maybe the two raids will settle the next one with compromise, sharing, a spitting-for-distance competition, or even a /random 1000 on their own the next time.
One word of caution I might throw about this idea..
Though it sounds like the right and just thing to do, If one of the raid forces is only there to block the other from progression (which is the case more times than you might think), Then you have done their job for them.
