Best jobs for my ping?

and using embolden in between the melee combo... I just feel very limited.

This is an unlikely to clip the GCD part. You have 1.5s to do only a single oGCD. If you're clipping from a single oGCD here, then I don't think any class will meet your non-clipping needs unfortunately.

I just wan't to play a class that doesn't clip to much.

All classes have the potential to clip, tbh.

As for the ranged classes:

RDM is has one of the least potentials to clip the GCD, if not the least. They also have least impact on your dps if you're not able to, since it just delays your burst rotation by some number of milliseconds instead of preventing a GCD during a phase burst.

BLM has the fewest number of oGCD to weave, but also the least opportunity to squeeze them in without clipping. It can also potentially cause you to lose a Fire IV from your rotation depending on your spell speed and how much you're clipping.

BRD has lots of room to squeeze oGCD in, but there are a ton of them and it can be random when you have to squeeze two in at a time due to their proc-based nature.

MCH burst output relies heavily on not clipping the GCD for a 10s duration, so it would not be for you at all.

SMN burst also relies on not clipping the GCD, although to a lesser degree than MCH. They also have a lot of oGCD abilities to weave in, so I wouldn't choose this either.

I'm not super familiar with melee rotations, so take the below with a grain of salt:

DRG has a relatively fixed rotation with a lot of oGCD which are generally only used one at a time, but there are a couple spots they need to use two at a time.

SAM is similar to the DRG, but their rotation is more fluid with a few spots where even a single oGCD can clip because they have a cast time for several of their abilities.

MNK only uses a single oGCD at a time as far as I'm aware, but I think this is because their speed buff makes it so that only one at a time can be used without clipping. They also pretty much are using an oGCD between every single GCD if you're okay with hitting buttons a lot. You might have luck with this.

NIN frequently has to squeeze 2 or 3 oGCD into a single hasted GCD, so clipping is the name of the game here. I don't think you'd enjoy this.
