Tiers for Bosses
It would be nice to have Tiers for bosses just like the players:
Bigger rewards, smarter AI, more difficult fights, and maybe deeper access to more important lore.
Example: A tier 2 boss may chase you out of the compound unlike a tier 1 boss. A tier 3 boss may do everything the other tiers would do but also use the environment like a player would or call zombies for help.
This would change up the game making it more engaging and give meaning to the tiers of hunters besides the looks. The higher the tier you get too the higher the boss you encounter. A tier 2 hunter can only encounter tier 2 & 1 bosses.
