I say not a cheese. Walking atheon off the edge back in the day = cheese. Host disconnecting during crota to keep him on his knees = cheese. Waiting for adds to despawn at bridge to self rez and shoot ogres = cheese. 10% ogres is just a new strat. that works well with some groups and works horribly with others. Your not going off the map here and your not doing anything wrong. In normal mode you did not have to deal with knights so no new strategies were made. Eather way you choose you should just make sure it works good for your group.
