Ayesh, this one would agree that the rewards are not worth it…
If this one had no PvP experience.

The rewards still aren’t that grand, not at the moment. The economy needs more building to make those coins actually useful. But there are signs it may go in that direction.

The biggest danger is lag.
The boss can kill one quite quickly if one is not paying attention or has a bad bout of new combat system over swing.

The fortress itself…
Well, it reminds this one of other players’ bases in one fundamental respect. One can often acquire the tools to destroy it from within the base itself.

It’s actually fairly good training wheel scenario for PvP. Learning how to deal with anti-climb, grubbing off the enemy’s own supplies, knowing what build pieces have how many HP and how best to reduce that number to 0.

This one does feel that the loot should be improved a bit. Give the Commander a Legendary Weapon perhaps? Or have a legendary chest or two in the treasure room?

Nimlot’s xp value is basically a trap. Follower thralls may well get butchered on the way in by the unending clown car of Stygian defenders.
The massive amount of coins can also be a trap unless you are already in an encum- er, expertise build.
