So I went and tested the barrage out a bit in CheatMod, and it appears the Pack Howitzer suffers the classic CoH 2 explosive design problem. It's really inaccurate, but hits like a truck when it's lucky enough to hit a squad.
Hugely unreliable, but incredibly powerful when it hits.
As a result, it's too much of an RNG cannon to be useful at clearing team weapons, but it's very strong sitting in the back line inflicting bleed and the occasional wipe.
The solution to this is pretty straightforward: damage down, reliability up. You can do that by squashing the AoE profile. It's what they did with the Brummbar.
Something like this, maybe?
- Auto Attack reload from 7 to 12.
- AoE radius from 5 to 8.
- AoE Distance Near/Mid/Far from 1.5/3/4.5 to 0.75/1.5/6.
This particular AoE profile is probably a bit too powerful (I reckon this'd outright kill any team weapon that tries to tank the barrage) but illustrates the concept fairly well.
