I try to do dailies, but Most of the strikes in the fireteam portal playlist (At Expert difficulty) don't support enough enemies to maximize the score, and the randoms just focus on DPSing the bosses down, rather then farm enemies to try and get the score topped off, to say nothing of the timer just getting ignored. It's making getting B-grade in matchmade activities increasingly frustrating to achieve, at least at the expert level. Enemies just need to be worth more score in these playlists. Otherwise I will probably just bail on the bad strikes.
