Very true. I have played both ways, and i prefer everyone down in middle. This way(it shouldn't happen with a good group) if anybody gets hurt bad chalice is close, and relic holder can easily take it back while swordbearer is being taken down before he strikes crota. There should be plenty of orbs about if you stay in that area and super enemies or use weapons/armor that have specs for orb generation, and time is spent only on swordbearers and crota himself. im not trying to argue or negate any bit of your case, just telling you the way it works best for myself and everybody I've showed this way to.
