What I want to defend is Regnums unique RvR.
I think it is ofcourse important to get new players and most of all to keep them playing - but the game should not be too mainstream, to me that would be devastating.
Instead, I think the key is to come up with something unique that blends into the RvR parts of the game and enhance it.
An example:
Dragons. They should not be normal bosses like in any other game, but instead they should live in the mountains where players can't reach them and roam the warzone and inner realm regulary. Invade cities, change the outcome of battles in WZ, etc.
Perhaps this idea with the dragons could also be used to manipulate realm balance.
When a dragon decides to take a flight "he will check" what realm currently is very underbalanced in a fortwar and go there to assist them.
When there is no action in the warzone at all, he would insead invade the cities to keep people busy all the time
Something similar could be done for the superbosses, but I guess NGD already got some general idea about how they should work.
PS. Edge, your idea with a premium item that increase the durability of the armor is great.
