It just feels like a clunkier to use lasrifle; tapping feels like it’s got a delay (presumably from the charging mechanic) so snapshots are tricky, chaining them is largely futile and iron sights make it difficult to get a target lined up compared to the reflex sight the lasrifles have. It becomes even trickier with the charge mechanic, because you either have to hold the target while charging, or charge and then try to line up a shot if the brief moment before it autofires.
Bayonet seems… alright. It doesn’t feel like it’s got much reach, which is what I was honestly expecting, so I’m not sure what it’s got going for it over your melee weapon.
