From my 20yrs flying the previous iterations of this thing, I would say co-ordinating the power - pitch couple with engine response and control force v pitch response is not intuitive because, depending where you are with respect to airspeed, engine response and stick pressure, a given amount of stick force produces wildly differing pitch response depending what the thrust is doing.
All of these are benign when used in moderation, but recovering from a low speed, high nose situation with large thrust inputs will rapidly lead to a PIO if the stick pressure is not very carefully co-ordinated with engine response, since the thrust lags considerably behind the position of the thrust levers.
