Agreed. People are clever and will figure out the easiest, quickest way to do things. Camping under the stairs at the archon priest was popular. The boss isn't hard, but it was easier to camp and not run around. Patched. That was technically an "exploit" according to bungie, but no one is banned. Sniping phogoth from the doorway is easier than dodging Knights and wizards. After countless hours in this game, figuring out new paths and hiding spots is about all that is left.
