As of May 9th 2021: can confirm it still happens on xbox one. I've tried testing many different methods of firing it in hopes of maybe finding a temporary solution, but to no avail. Crouching while activating, firing it away from you, firing it directly downwards at your own feet, not looking upwards from the ground until it engages and starts to fire, (I thought maybe it was a byproduct of raising the crosshair in an upward direction during the activation frames somehow causing it to take the upward aiming trajectory into account and continue to rise as a result, [overthinking it] but this wasnt really leading to results either) etc. Nothing seemed to work as a fix, so it seems completely random. Unfortunate as it kind of wastes the magazine in cases where it does happen, but if used with mirage it somewhat overcompensates by launching 3 instead of 1, raising chances of getting a successful disc launch that actually makes contact with enemies. Besides liking to see it fixed, I think slightly reworking it to fire in 5 - 6 directions (like a pentagonal or hexagonal vertices formation) instead of 4 would help the weapon with applying more sustained and consistent status procs on a single target in an area, therefore increasing its effectiveness on all enemies in said area. Otherwise, fun weapon, v cool, pls fix.
