On the matter of Healers: Thats why i suggested reducing the overall amount of Healung abilities. On WHM matter, to provide a example, Cure 1 could simply upgrade just like any other skill into Cure 2 and then 3, and that would in theory, already make Room for 2 additional Spells which could be Dps Abilities.

On the matter of ARR, it is indeed, very slow and thats why downshifting Skills would be a good addition. Since it directly makes the Player more powerful, simply for having more skills avaiable, it can also be used as a opportunity to buff overworld, as well as ARR/HW Dungeons (especially the former) since most enemies in that content, just do weak AA dmg and easily dodgeable cones or small circles. It would be great if they also get more skills/dmg or HP and said changes, would give reason to do so.

The pacing on the EXP matter, isnt as bad as People claim it to be, for MMO standards. Many MMOs are way grindier and give far less overall EXP. FFXIV is extremely generous in that regard.
