The KE-Sabot rifle is the Reaper's secondary weapon, which offers lower burst damage than the Sharpshooter's Sabot rifle with better DPS. However, the KE-Sabot's DPS does not compensate for its lower burst damage; with equivalent primary weapons, the Sharpshooter also has a faster TTK than the Reaper against any mech before considering the Sharpshooter's damage-modifying ability.
Damage output typically is not tied to mech class. The Vulcan Berserker will have the same TTK against any mech as the Vulcan Brawler and Vulcan Assault. Same with the Flak Brawler and Flak Scout. Even the Raider and G2 Raider have balanced TTK's with DPS and burst variant secondary weapons. My suggestion is to balance the Reaper's damage output with the Sharpshooter's, just as other mechs with comparable loadouts have equivalent damage output regardless of class.
Currently, the scoped KE-Sabot does 75 damage per shot.
To match the Slug-Sharpshooter's TTK against the Assault with the Slug-Reaper, the KE-Sabot would need to do 80.22 damage per shot.
To match the AM-SAR Sharpshooter's TTK against the Assault with the AM-SAR Reaper, the KE-Sabot would need to do 82.95 damage.
Currently, the Reaper's scope provides a 1.25 damage modifier to the KE-Sabot's damage.
Suggestion:
Increase scoped KE-Sabot's damage from 75 to 80-85.Increase unscoped KE-Sabot's damage from 60 to 64-68.
With the upper bound of this change, the Slug Reaper's TTK would break even with the Sharpshooter's TTK at 410 damage. The AM-SAR Reaper's TTK would break even with the Sharpshooter's TTK at 486 damage. The Sharpshooter would still have a faster TTK versus light mechs, whereas the Reaper would have a faster TTK against B-Class and C-Class mechs as would be expected from a DPS-oriented sniper variant - ignoring the Sharpshooter's ability. With Powershot, the Sharpshooter gains a faster TTK than the Reaper against any single mech.
Note: TTK is approximated assuming perfect accuracy based on TTK = (armour - burst)/dps.
