I know the Tesla Tower isn't "good". But I love the idea of just zapping the shit out of anything that gets too close. Being a team killing machine is just a bonus.
People spent too much energy and focus on 'what's good' that they forget to have fun. My mates and I bring whatever we feel like in missions. We run on 7 most times sometimes we crank it up to 9 for the heck of it.
Biggest reason I don't do multiplayer any more. Even when it's not competative, there's always at least one piece of shit more interested in angrily grinding out wins than having fun.
