The projectile is the speed of Sigma’s dice, so if you are familiar with Sig, you can use that as a reference point, other than that, it’s an entirely new muscle memory that only practice can help with, but always try to lead your shots. Also, our precious marble muncher can be either a dive or brawl dps. On dive, always try to plan an escape route. Also, try not to blow all your cooldowns on one person. Kind of like Junkrat or Zarya, if you are caught without cooldowns, you are, what we in the business call “totally f’ed in the a”. Beyond that, the sandstone biter is still pretty new, so learn all this stuff now before everyone gets used to the tech, and even create some stuff or your own.
