@DYSPROssiumI have no idea what those numbers for speed mean, but from my tests they have almost absolutely no correlation with reality ingame (e.g., mastiff bullets are actually faster than wingman).
That may be initial bullet velocity (in some imaginary units), or some coefficient, but apparently that's not the only number determining bullet travel ingame, e.g., the may be very significant velocity drop over distance and that varies greatly between weapons.
"There is no difference between Wingman and Longbow"
Good joke. XD
Have you ever USED the weapons? You can write a poem in your head before a mid-long range wingman shot reaches it's destination. Even R99 bullets are significantly faster.
(At 750m, after shooting wingman, I switched to Kraber, ADS'ed and still had to wait a while before I saw the bullet hit... - maybe the poem would be just a few lines, but could certainly do it)
Anyway, numbers on paper really don't matter (unless you have ALL the relevant numbers (actual initial velocity and velocity drop curve)), what matters is what actually happens in game. And I can assure you, L-STAR bullets are in no way slow. Go test it yourself.
Also L-stars bullets are enormous, so you really wouldn't need to lead your targets at close range, even if the bullets were as slow as you think them to be.
The muzzle flash was a huge problem for L-star when it had no sight, now it doesn't feel any different from havoc or devotion (which are flashy, but definitely usable).
P.S. Muzzle flash IS a generally big problem in Apex altogether, but that's a completely different topic.
The only reason why I (and probably most of everyone else) usually avoid the L-star and/or fail with it is that I'm too trigger happy and I consistently overheat it (I just can't force myself to stop at 8-10 shots, even if all I need to do is let go of LMB for a millisecond...). But that's really my problem, not the weapon's. L-star is a heavily underestimated monster weapon.
If you think that finding L-star in package is a disappointment, then now honestly try to imagine how you would feel finding a CR (in it's current state, not buffed) in it... Most ppl don't even pick it up as world spawn, so you can't actually honestly think it would be fine in a care package...
