MG-42, Bren, Vickers, Schreck, Bazooka with any of these weapons. Conscripts will be better than the 7th person. I prefer an aggressive style of play with significant microcontrol. So a weapon upgrade is more useful to me than a bonus of accuracy from a static state. I do not need this illusory merger bonus.
Well, it’s possible, but the weapon bonus always works regardless of the attack / defense or cover / out of cover, the 7th person bonus accuracy works in the cover, and it’s problematic to find a cover 3vs3 or higher with constant artillery fire when the whole map is one big red cover. Maybe this is just my bias, but my game experience tells me that weapons is better than the 7th person.
...because of this we come to the strange concepts of the 7th person inventing strange roles for them. And I continue to think that we should remove one infantry unit and make the remaining unit competitive for the starting infantry of the remaining factions.
First, 7 man conscripts do not gain accuracy, they gain reduced cooldown and faster reload, and second they do not need to be stationary to receive these bonuses.
As vipper already mentioned, the weapons you brought up all require your unit to be stationary, and contradict your second point about not liking your units having to be in a static state. Not only that, you are relying on rng drops to upgrade your troops and you are assuming your allies or your enemy don't get to them first. That's like skipping medics to rely on your opponents dropping medical crates in bad positions so you can steal them and heal your troops
I'd also like to point out that rocket barrages, howitzers and off map barrages do NOT create red cover, they create yellow cover. Particularly in larger game modes where these are more plentiful, the terrain ends up being saturated with yellow cover resulting in 7 man cons almost perpetually receiving their cover bonuses.
Other things to note is that if you feel the merge advantage 7 man cons have is "illusory" then you are obviously not using merge enough or properly.
There is also no "strange role" that 7 man cons get. They flat out have a massive damage output increase due to both the cover bonus AND the additional man, they have an increase in durability due to the extra man, they are far more cost efficient because of their reduced reinforce cost and they vet up extremely fast because of the damage increase coupled with additional experience gain. Literally it takes everything that cons can do at the start and gives them a huge buff.
Early on cons are fine. They are faster and more durable then anything they face. When upgrades come out then indeed they are weak. Their durability advantidge becomes rather obsolete at that point, without ai upgrades to cover this they just suck mostly.
The 7th man corrects this and gives them the durability advantidge again.
The problem is that it is still "early game" at the time german troops start getting weapon upgrades. And even before that, conscripts fare rather poorly against the OKW early game lineup and also quite poorly against specific ost strats/commanders (eg assgrens).
