Nerf inc to keeping low level followers..( for the purpose of getting low level missions )
Originally missions all pulled from a single pool; players found that as they got their first level 100 followers they got fewer low-level missions and had a harder time leveling their weaker followers, so we made a change to ensure that some low-level missions would always pop if you had a follower in that range who needed them. We recognize this causes some odd incentives (you're encouraged to NOT max all your followers) and are discussing good solutions to that problem.
