No... It'd compromise FFXIV's identity imo and make it too much like other MMO's.
The combat system is built around it the PvP combat already feels rly dumbed down as it is.

The reason why there are 1 button combos in PvP is because the combat just isn't suited for PvP inherently and they have to change things for it to make sense.
Same reason why positionals are not in PvP and in PvP you can't rly have a rotation like you do in PvE it's too inconsistent.

I rly don't understand either why some people are so obsessed with pushing as few buttons as possible.
Most Jobs in FFXIV are fairly busy but I wouldn't exactly call it overkill I feel like they're in a pretty perfect spot overall
If you want to spam the same few buttons over and over again there's games like ESO or WoW:

Most rotations are already fairly streamlined this would only make it even more repetitive.
Not to mention how Jobs would have to straight up be redesigned.

I mean you play MNK too, surely you must realize what a complete nightmare it'd be in PvE and how it'd screw up your rotation as soon as you drifted?
Your ability to adapt would be compromised.
