Good teamwork being OP and this kind of OP are two completely different tiers. This is about as fair as spawn camping (you know the kind where all I have to do is hold down the trigger and enemies spawn into my bullets). What is interesting about having 4 titans spamming their supers, and 2 other guardians feeding off of it? I tried to come up with exciting examples of exploiting game mechanics that make PvP more exciting in games, buy none come to mind.
