It's not that simple, you need both in the arena at the same time. The conflict of interest is what drives the game. Without the base takers, there is no stimulus to start or keep fights going, with out furballers, there is no MMO aspect of the game, as we would all just take undefended bases where we battled ack and the clock.
The base takers are going to complain when they feel they are unable to be successful. The fur-ballers are going to complain when they can't get any fights. The trick is finding a balance where both sides feel that the have a chance at being successful. Its keeping that illusion that inspires hope and keeps the war going forever.
There is also the dynamic as there are less new players, the newer players resort to lager groups to accomplish their goals, hence creating more whines. These whines then translate into changes to balance the trend, as the mega horde is a response to failing when they are not in hordes. Lastly, other than eny, there is no game mechanic to keep hoard size in check, so as the balance of skills & goals of the player base evolves we can expect even larger hordes as there is an apparent reduced risk and increased reward for doing so. HiTech, attempted to address this issue by changing the radar but that didn't work as he intended.
