My point with this was that, even with current design, Penals don't need an additional weapon upgrade or similar to boost their DPS. A Penal squad right out of the barracks is about as good as other mainline infantry with their weapon upgrade purchased. And no one complains about other mainlines being too weak if you rebuild them.
Conscripts on the other hand suffered a lot before Mobilized reserves, because both DPS and survivability were bad at vet0. Even cheap Conscripts were bleeding you heavily because it took them ages to get vet 2 due to low damage. All of this got adressed with Mobilized Reserves.
Saying that old Conscripts and Penals suffer the same problems and need the same treatment is in my opinion straight up wrong.
That's true, they suffer DIFFERENT PROBLEMS (at similar stage in the game) but they are been treated as it can be SOLVED in the same way.
Vanilla conscripts were fine till the moment they nerf all the alternative ways for the faction to wipe and do dmg (mines, flare, demos, T70, maxims, free barrages, power of doctrinal units) Which is totally a valid design choice but it took mobilize reserves in order to fix the problem.
I have issues with the line of thought that throwing vet will simple fix problems.
There are several units which are getting nerfed on this patch and there are a couple more than SHOULD be tweak as well, but i think a proper compensation/rework is due in other areas.
