The only people playing haven are either bot factions or new players who haven't gotten to the grinding stage yet. There is also a select few that stubbornly refuse to use bots. Noone in haven would stick around doing farming trough food for cows another 12 months by hand or some of the other heavy task demanding jobs. Its to repetitive and grindy doing it manually. This is the 3rd world in a row with no changes other then a complete reboot. People have grown tired of the game as everything have stagnated explaining the low player count. Bots in fact is the glue thats currently is keeping the few people around still interested.
You should also note that PvP in haven is not about stats or infinite steel/cheese/curio production. Most pvpers find time to pvp and therefore do less grindy stuff i.e. bot stuff. It doesn't take 1000s of stats to go raid a noob. All you need is 2 friends with 200UA and 100 STR and your set. You can get that in less then week without bots and just about every noob that gets raided gets killed by shitty developed alts that people run around with killing noobs for the shits and giggles.
People that bot often do so to compeat in the arms raise so faction A wont fall behind faction B. If your dumb and situate yourself on there doorsteps then it doesn't take a genius to figure out your at there mercy.
This is a survival sandbox. Figure out how to survive or leave the game like all the other quitters before you.
