We will see what happens next expansion. When Endwalker started things were not as easy as they are now, and there is a problem with the kind of game FFXIV is where once that first .0 launch patch passes, content gets easier and easier due to the world and everything staying at the .0 scaling, while everything after might go up in scaling, but generally ends up being easier anyway. It also ends up in a weird scenario where patches that introduce a new savage tier tend to have the hardest EX fights, because no one can outgear the EX fight severely over the baseline. The EX fight that follows is always out scaled, so it ends up being far easier. Savage has this thing where the first two savage fights are scaled for the patch that the savage launches under, and the last two are scaled for the patch that comes after the launch of the tier OR if the players grind the first two to leapfrog that patch. Technically, pentameld doesn't leapfrog as much as puts someone at the baseline needed to complete all tiers of the savage if they really pushed hard.
The issue savage has is that the content grows stale very quickly and it doesn't feel good to prog after the followup major patch on the current tier. That and as stated earlier, it is sort of turned into the only viable way to get a meaningful reward due to gear level being objectively better than any other option.
