Hi there. Since I play this game, tons of things have been modified.
Since there are new monster dens, I was thinking a second hero could help to improve the gameplay.
One of them, the secondary hero, could deal with new monster dens (only) like a housekeeper could do or open chests in our towns.
The main hero could be the only one able to attack other gamers or to go in quest spots. Why this idea ? It could be more handy to visit many places with one of the hero and the other one could open chests / fight monsters in dens to avoid them attacking.
Since we already have some NPC inhabitants with the treasure seeker or Eluia (the daughter of the Keeper's village chief). Then they could be useful and expand the main story by the way. He or she could gather some XP with the troops during the attacks against new monster dens.
