Posting for DianaP server 8 who isn't able to acces the forum atm:

Arena:
I think arena is a nice feature in game and should stay one for each realm, as you need to keep alive competition within a realm. I would suggest though to make the below changes so players will visit arena more often:

- In order for a player to participate in arena to pay a weekly fee (not very high - this fee is only to help you keep in arena active players)
- Since there will be a weekly fee, rank will be reset and players will now have an incentive to start working for top rank...


Warfare:
In order to avoid server merge to one big guild i suggest to keep cities for lvl 3-5 guilds in realm bidding (maybe reduce cities and make buff % higher) and cities for higher level guilds be server bidding.


General feedback:
This is a nice game and i really enjoy playing it! We hope for more competition between realms so the game becomes more interesting.
