Simple things for me: Remove the overheat mechanic.
Make the job more intuitive. I could be using and aligning all the cool downs I can but messing up is way too easy and Wildfire only adds more stress for not that much gain and even then I have no clue if all that action is getting me average DPS or not.
Make the turrets be able to follow you. Take a hint from Nier Automata since it’s coming to play later. While we are at it, give the turrets more moves. Make it like Enkindle but obviously not that powerful and not on such a long cool down.
