I don't know where the feedback is supposedly coming from but quite honestly I think we need more time before any of it can be taken seriously. I find Viper to be incredibly easy to understand and play and the speed makes it fun. Understanding which positional is coming up (which is easily identifiable via color) or when to save and use my ranged combo is very engaging and fun. The class is somewhat faster than other classes in FXIV that I have played, but not really much faster than others and it doesn't really feel busy, it just feels like it doesn't have any dead air (WHICH IS A GOOD THING).

Please reconsider any changes you are jumping in to and see how things work out over time before making major adjustments like simplifying a class that is already very simple.
