As newer, better gear becomes available via heroic missions and operations, players that don't group often are stuck with the same gear as before. We want to earn better gear. Yes, EARN better gear. But if grouping isn't really an option, we can't. We need an alternate way to upgrade our gear. Not to say it should be as good as endgame, but something better than before.
Thus my suggestion: LITE gear ( similar to the latest, but with fewer calories...er , stats). Go ahead , make it expensive. Obscene amount of daily tokens, credits or even special random reward tokens from dailies....make us WORK FOR IT, but give us an alternative to having to get in groups.
