As an extremely PVP/efficiency focused person, I'm fairly concerned about this too.
PVP is generally going to be more of a hurdle to efficient resource gathering for most people, than anything that's likely to be put in the furrylands. Furryland will likely be over farmed because of this, devaluing its resources. Presumably once furryland resources are devalued enough, the risk:reward factor would lead most furrymen to travel elsewhere for a better paycheck. Past the initial release, I'd also expect the new player population to be highest in furryland, leading to a greater reduction is resource value.
Alternatively, the value of resources on the furryland may be artificially increased, forcing PVPers to farm there on alts. Lower risk, higher reward.
Just sayin', being a sandbox PVPer doesn't mean you're inherently some over testosterone filled butthole out to ruin everybody's experience. I feel the majority of people who act like they are, are just extremely unpleasant people who don't fare well in social situations. People that others quickly end up disliking. People who instigate name calling, while simultaneously acting morally superior. Annoying people.
With that in mind, given the opportunity, I'm going to corpse camp the poop out of you.
