I am not a hardcore fighting game player anymore; but back in 2019, a pro fighting game player named Momochi commented on how many fighting games are taking the 'if we make it easier, then more people will play our game' like how the FFXIV devs over simplified the healers and tanks. In his argument, he states that simplifying the game doesn't generate new players. Rather, most still quit either way, and the oversimplification of the game frustrated veteran players, causing a split in the community. At worst, some veterans even quit! This happened with Street Fighter 5 and Mortal Kombat 11, and I believe the same exact issue is happening with the healer and tank communities in FFXIV.
Making the game easier won't fix any problems as good players will always do good and newbies with no patience will get frustrated and quit. Tanks and Healers are still played less compared to DPS classes. Making the jobs easier did nothing! All SE did was frustrate veteran players by limiting their playstyle and removing job identity.
