Conan Exiles rather depends on thralls for decent game play.
Since wild Surge crafter thralls are, inevitably, Level 1, just barely above useless, I’d like to suggest a leveling system for thralls. Level 1 thralls would, slowly, level to 2 and then 3, depending on crafting, which is dependant on resource gathering, which keeps folks engaged.
T4 and 5 thralls would still be a product of triggered surges, but, with T3 thralls, players could feel some progress rather than being stuck at level 1 until the chance to get a T4 of 5.
Tie the thrall to the station, so if they are removed, they revert to level 1.
As it stands, the lack of decent level crafting thralls turns the game into a unhappy grind.
