Penals are just an end result of legacy Soviet teching design, we can go in circles all day talking about game design and past balance decisions but at the end of the day this patch is about improving core armies and meta problems.
I agree that talking history is of little help especially if it ancient history about thing that have little relevance to current state.
As long as Penals are made a less obviously bad choice to full conscript builds without making them OP then that should be enough for this patch.
One of the problem is thou that Penal have been in the same state for years and yet they went from dominating the meta and now they slowly falling out a favor. So the solution does not actually lay in buffing the Penals since Grenadier and VG are at there limit and ready to fall apart.
Unless you want to argue that late game utility buffs or PTRS changes push Penals into OP territory or that your changes achieve a better result in helping Penals function as a non-doc unit then we should stick to talking about the proposed changes because I doubt the balance team has the appetite to redesign Soviet teching just to solve the T1 or T2 only problem just to have "better game design"
Well the problem is that "band aid" approach applied so far does not work, so imo one should either
solve the problem or not touch it at all.
There are many different solution one can choose from.
If T1 need an AT infatry/or AT Solution then T1 should get a proper AT Vehicle infatry (with proper cost/vet bonuses/abilities timing)and not chameleon that is push and twisted to fit every role out ther. That is simply a "lazy" solution that in end create allot more problem that it solves.
There have been endless thread about Penals over the last 4 years and imo the majority of them say the same thing: Penal are simply badly designed trying to cover to many roles at the same time.
