castle 1-5 should be on its own server that all 1-5's join.. continue this process to combine all the players together. To continue your castle progression u need to move to the nxt server. Have open worlds that all can join and other worlds for special events etc.
balances the power issue with merges atm ..
puts current power lvls into a similar power environment
npc's on the server can be scaled to suite the current power lvls
allows constant healthy progression finally reaching end game server
removes the bully aspect limiting power for each server
All get a turn at being the power on the server before moving onto the nxt tier
groups the community into about 10 servers based off current max lvl, giving alot more player interaction
This would actually be a sustainable model which would allow them to continue to increase the max lvl as the endgame server fills up, while stil providing safe, yet exciting, early game areas for ppl to explore and conquer.
The house system would need a revamp as there would be issues using current system.
Servers with so many players would need to be lag free , but instead of running 1000's of small 1's they only need afew large 1's...
The way the current merger system is toted to take place with deathmatch style, handpicked server battles. i just cant see the longevity of those decisions..
