Another one from RelicWiki:
The Dark Reaper Exarch's Reaper Cannon does not scale well against Infantry and Vehicles with Optics upgrades, as compared to its squad members' version.
Of note is that the Exarch begins with an extremely low DPS value of 3.0 against all VEHICLE_* armor types.
Regular Dark Reapers with Improved Optics and Superior Optics upgrades scale somewhat against VEHICLE_LIGHT and VEHICLE_MEDIUM armor, while the Exarch's DPS values remain at 3.0 against all three types.
Of much greater note is that even with both upgrades, the Exarch's DPS values scale poorly against most INFANTRY_* and HEAVY_INFANTRY_* armor types as well as MONSTER_MEDIUM armor.
Again, regular Reapers with both Optics upgrades end up dealing much more damage to Infantry and Heavy Infantry than the exarch, when considering that as a leader, he is supposed to excel at this role.
