They need to find a way to balance. I'm not saying it's the perfect solution, just saying there are PVP elements in PVE servers of other MMOs. Being such a vital part of the game, it is something the Devs will have to be careful what they do. I just know it feels terrible logging in to find everything you put 20 hours into, stripped and reclaimed, but at the same time you don't want big Companies to own the entire map. Perhaps putting a diminishing return on the claim flags the more area your company has. So if you have a small area 1-2 flags it takes say 24ish hours for another company to try to claim it, but if you have more say 10ish it takes only 5hours, 20ish 1hour. The initial claim should take significantly longer the more territory your company owns.
