So let me get this right; in order for me to progress the catalyst I have to sit around while my teammates get kills with Rat King? Like literally sit around not helping because they have to get the kills and not me. That's terrible. It should have been something like you need to get 3000 kills, but kills while Rat Pack is active count 3x as much. This way you can actually can do it solo but you're still very much incentivized to do it with a group. It's one of the only good catalysts and I really disapprove of this non-gameplay required to get it.
