mir is a mmorpg game (keyword rpg) as as such its base is pve (with pvp in secondary place)
point here is that if starting on mir server all pple did was to infight btw themselves (pvp) and nobody hunting in caves to get exp points to level plus items from drops (pve), then the game wouldn't progress and maximum satisfaction you'd get from pvp, besides the 'top of the hill' feeling would be if someone you pked dropped you an added stat ebony sword
(and even that depended on pve gameplay in the first place)
pple oriented more towards rpg, that is pve element tend to make quest dependent gameplay or at least supply many quests and typically it is low rate server, on the other hand, pvp oriented pple who make servers tend to skimp on quests and typically make high rate server, what you get depends who makes servers these days
DarkZone server, now in beta, if I can judge from playing DZReborn server, shouldn't have many quests and be more for pvp minded pple
