I too would like the cap to stay at 99 or 100 for every expansion going forward. They're already having a hard time trying to fill in the spaces between levels (which is especially bad for jobs like SMN, or the healers) whilst trying to stay under a limit of too many buttons. We can see this with how many useless fluff traits the game has like Melee Mastery or Maim and Mend that are there only to fill in the gap between levels and nothing else. Increasing the level cap even further is only going to make this problem worse.
