Can already tell the Jack O Naut mission will be fun

It's trivialized by Wukong + Zenurik Inner Might. Inner Might lets you cast clone (and Cloud Walker after a 1m cooldown) for free. The clone is not disarmed and will instantly shoot down the boss and other low level enemies with your primary/secondary. Wukong is also a strong choice for the second mission, which has a low energy capacity and regen modifier. The third mission doesn't mess with your energy so you can just bring a nuke.
