I would expect these spells will be in the game. The current level cap is 50 and im sure they will raise it in the future, with new abilities and spells, as in FFXI.
The level cap will be raised, it has to be raised.
If it is not raised, then easily 60% of aetherite gates and camps are completely useless. Also, a stupid amount of monsters will be able to one shot anybody, making them inaccessible.
Look at La Noesca. See South Bloodshore? Those monsters can one shot me at R40.
If the level cap is 50 forever, then south bloodshore is a complete waste of space.
And there's a lot more than just that one area
