Stone Hurlers have some preposterously big disadvantages.
The first one being terribly short range, meaning you can`t safely place them in any scenario and against any troops. Any sort of cavalry is just going to cut trough them as they can close the distance without the Hurlers firing.
The second one being their dreadful mushiness. There`s really no point in taking a bless for them either. Earth means nothing for archers and regen means nothing to monsters that can`t sustain themselves on the battlefield a few rounds for the regen to take effect.
And in the end they have no protection, no shield, no defense, so any combination of cannon fodder + archers will kill them.

They`re good and they have many uses now, but I doubt they need fixing. Besides, there are better nations with much better sacreds for the same gold ratio.
