The joke is that, like Destiny's loot cave, they were quick to fix a way that players could actually get loot-- maybe some of it useful-- but are going to make us wait until TU 3.1 for the AI fix, which could still be weeks away. Destiny had many of its own problems at the time, including getting useful loot, which is why the loot cave became popular.
They already said they identified the problem in the last SotG, so they SHOULD release a stand alone patch that fixes the AI behavior. They won't, though, because they apparently have to pay MS and Sony some money to get the patches validated. So in order to save a few bucks, they'll make us wait up to the next month with this borked AI and wonder why the raid isn't being completed by as many people on console as it could be, because the AI moves too fast to aim at and dodges bullets like Neo.
