I came from SWG where forward camps were abundant. However, the planets were massive and you could not walk or speeder your way from a major city to a battlefield. Cyrodil is not big enough to use the camps how they were and frankly large guilds abused them by placing them in such a way that a keep never ran out of reinforcements.
I do not want to kill 10 players and it make no difference as long as somebody can get a camp up on another tower. I want the enemy to feel their forces dwindling and have to have the heat and adrenaline running through them when they ask themselves, "Is there a spy squad over this hill?" when they are running as fast as they can to a combat point.
If they do decide to bring camps back in, make them truly costly to purchase so that they can reflect their massive tactical advantage. For now though, well done ZoS.
