Nope. Balance team would never go for standarized vet.
ironically they are
standarizing everything. veterancy is really one of the least visible aspect of the game.
As if there wasnt already way too much mirroring.
Especially some of the changes during this patch were already a way too high cost payed in uniqueness, for (not much better) balance
how else would you make the line infantry veterancy unique and still balanced?
jp4 and FF veterancy are different, but I would say they are still "equivalent". FF offer more offensive bonus and JP4 offer more defensive bonus. Some people are obsess with the 40 bonus damage on the FF without taking into account the whole package.
right now rifleman vet is basically outright better than volks and grenadier.
"asymmetric" doesn't mean making one side overpowered.
right now the rifleman vet is 30% acc, 15% def + 23% def. that extra 15% def basically wipe away the extra acc bonus on the grenadiers.
alternative: 1.3 x .77 = 1.001 (rifleman vs gren)
1.4 x .77 x .93 = 1.002
