It isn't really about between Ricoshet and Twins, but about Short Range Turrets (Hammer, Twins, Ricoshet). They all are getting a negative change in terms of range. Meanwhile, Melee Range Turrets (Freeze, Firebird, Tesla, Isida) are getting their range increased. It was probably done since players complained about melee turrets having certain disadvantages in some Matchmaking conditions (eg Maps, high-range turrets camping, etc). If so, that would make sense. Also, I tried playing with Ricoshet (Berserk augment, which doesn't affect the changed, in this patch, aspects of the turret), and the plasmas were disappearing before reaching their Final Projectile speed, so I dont really see a change here.
