I will agree the mechanics of the raid are not that hard but I don't believe that you run a 30 through hard mode without doing easy methods, be it having a hunter solo the abyss, you would have to either cheese the bridge let the 30 die on the first side or have them give the sword to someone else since they can not kill the gatekeeper, or doing the center strat for Crota. Also for the Crota fight if you have the 30 stand back to not take damage you are making the raid easier so have them out in the battlefield as well.
