I would like to see mass battles with npc army/groups perhaps as a raid with waves of enenmy attacking guild cities or just even an open field. Perhaps throw in a real hard epic boss general too.
Need to be random so the type of enemy changes and from where they attack differs.
Should also have random drop of epics like a raid from a random npc. Sometimes one drop sometimes 3.
To start it like a raid with raid leader similar to the 24 man instances.
Also be cool to have 3 man instances small instance that covers the land completing different tasks. Like a mini raid but again random not like BRC and HM's where everyone knows whats going to happen!
My thoughts anyways.
