Getting some extra keys for playing non-preferred is okay, but what if I have plenty of keys and I’m trying to level a certain character to 40?
Solution: Split XP (50/50) with your preferred Hunter in addition to the extra keys. Now you are leveling 2 hunters at once and getting free keys.
This should only be an option. Like it should say “Split XP?” and you would answer yes or no. If you answered yes you pick the hunter you are splitting XP with, and then select the hunter within your assigned role that you will play, select perks, etc.
This would also reward players that want to play their favorite hunter or monster after they have leveled them up to 40.
