I am a guardian tank, awesome experience, I know which buttons to press, actually if I hide the UI I still know which buttons to press, but I am awesome too.
Adding an option to switch off the part that can cause headaches/nausea for those that are light sensitive should be in the pipeline though, maybe when the UI modding is done, probably faster if enough people complain though, which is what everyone (or 99%) of the people on these forums do anyway.
