And exactly my point once more. Penal need better accuracy mid not far. If one gives 200% more accuracy far the benefit at range 20 would be only around 14% while the DPS total weapons area profile would be increased dramatically. On the other hand if one increase mid range accuracy by 15%-20% the weapon would benefit at range 20 about the same, without dramatically increase the performance.
A 20% buff gives Penals a whole 5% more dps at 20 then cons....
Not sure why you want to make Penals work only @ 20? It creates a highly specialised unit out of what should be mailine infantry. Close range units can still close the distance, no use at all at range, its just bad design.
The weapon profile as it stands is plain bad, 200% at range sounds like alot but it just brings them inline with rifles.
Alternatively you could increase the short range dps, but that wouldn't make the most of the flamer and steps on ppsh cons/shock toes.
