I saw most of the threads about the new thrall system were based on the follower limit. My concern is of the leveling system itself, and I’d like to offer some concerns I have.
From what I can gather reading the posts by the devs and watching the videos, existing thralls (and likely captured thralls) won’t change much in terms of stats. That is, existing thralls will be about the same, and capturing a new thrall will be about the same as it is now, but that new thralls placed will be able to be leveled up. My concern is how powerful these thralls can become. I can take a single berserker, give him some heavy armor and a decent greatsword, and clear out New Asagarth or Mounds of the Dead. Most world bosses lose against him, and even the toughest ones only require some assistance from me.
If this thrall levels up and becomes stronger, could it be game-breaking in the sense that all vanilla content becomes far too easy?
