Scholar has the worst design of any job in the game, and here's why.

Lilies are heals though. Mobility tools are things like Lightspeed, Malefic, Triplecast, instant damage GCD's, leaps, teleports and so on. WHM burning it's lilies to move are one of the reasons it has an identity of either being carried by the coheal on healing just to do below average rdps, or doing poor dps just to heal well.

I'll never understand WHM's identity of "strong GCD based heals". All it has over the other healers is Cure III which has a terrible range and is rarely needed. That's it. It's entire "GCD identity" is built on one niche and unnecessary heal. All the other heals are overpriced copies of Diurnal AST heals and lilies are burnt on moving or intermissions and inferior to AST/SCH's oGCD heals.

Lilies are not just heals. Lilies serve 3 purposes, they are used to move, they are used to weave because they are instant, and they are used to heal. WHM wants to use lilies to cover all three at once optimally. You can use lilies at max HP to move, because it gives you some damage return, and the potency return is higher than that of clipping your Dia. Ideally, you let your party stay lower on HP so that you can get some healing when you need to move. If your cohealer wants to be a heal bot that doesn't let you do that, then so be it, they can waste their resources for you playing correctly.

WHM's identity is literally its GCDs. WHM doesn't have the weaving space to properly use oGCD heals, and its entire design forces you to use GCDs. Its whole design is around using GCDs to heal, with things such as plenary rewarding you for doing them.

Ehhhhh, was it though? It was a huge problem to be certain. I think another major contributor was the fact that Diurnal AST was "WHM...but better!" Its heals were nearly the same potency, sometimes even higher. Better mobility. Stronger rDPS. Actual utility. Especially after the Malefic buff, there was no reason to take a WHM. It brought nothing to the table AST couldn't do better.

Poor mobility doesn't help there, but having no strengths that the other two healers can't do easier and cheaper, while being totally unable to do several of the things they're capable of... that's a nasty weakness.

Yes, it was. WHM reached the dumpster last expansion after repeated AST buffs, but it was also in a horrible tier for the class design wise. In E9s-E12s you had to deal with the likes of Pantokrator, Hello World, etc. WHM had no options to cover that movement, which severely hurt its DPS. This stacked on top of it not having as good rdps anyway made is compound its weakness.
