You want people to want to keep their sub and be playing every month, not sub a month every few months to try out the new stuff. A look at recent mmo's success or failure as well as WoW's sub history only proves this. If players don't feel the need for a long term investment in the game, they won't stay constantly subbed. Name me all the successful pay to play mmos you can think of that are casual, excluding wow (which I also addressed above, was at its peaks before it was over-casualized has declined ever since).
I will agree accessibility is important and bars should never be set too high or it will be forever niche, but over-doing the opposite side will result in a similar fall albeit in a slightly different way.
