Crota End Hard Raid Help

i haven't beaten it yet and would like people help to end my nightmare. i would only like to beat it enough to just get the Fang of ir yut. that is my only reason for doing it. i can do the abyss fine but the bridge is hard. most of the time people want to cheese the bridge. i have also done the deathsinger with 50% success. i haven't done neither hard or normal yet as of this reset. i'm only 7 radiant shards from reaching lvl 32. i'm and lvl 31 warlock with max gjallarhorn, icebreaker, vex mythoclast, thorn, suros regime,
