1 In relation to their speed or damage/pen? Would even a price increase help there?
If you only increase the price, that's going to make Brits the new pre-rework OKW, especially in teamgames. There, camping it out and getting armour meant you could steamroll anything the enemies could field by that point.
3 How so? STG's/BARS/LMG's are no brainers, what would make Brens less so? Bring them in line with the aforementioned? No problem with that.
- STGs are almost no-brainers, except for the fact that they take up both slots.
- Bars, in theory, prevent you from getting LMGs. However they are no brainers anyway. You wouldn't put bazookas on Riflemen either, anyway.
- Grenadiers have non-negligible DPS on the move. Currently the only faction Grenadiers can use that and get away with it are Soviets. Thus, the LMG42 is at least a quasi-no-brainer.
Tommies, unlike other non-ostruppen squads in existence don't have mobility at all (moving DPS). They need to stand still, and at range, to hit anything. Thus, upgrading to Bren guns is a no-brainer.
4 What do you mean by frontloaded?
Vet0 Tommies in cover start with a 0.72 received accuracy (compared to 0.91 for Grenadiers), with rifles that have better DPS when stationary. Part of that received accuracy bonus could be postponed and moved to later Vet levels.
5 By all means, it's useless anyway as it comes far too late and doesn't engine damage heavier vehicles
Having access to snares means that enemy LVs can't just yolodive for the sniper. This would allow the sniper to fire with near-impunity and get to Vet1. At that point all LV investment that the enemy has made is in danger.
Also note that the Brit sniper is the only sniper with 100% accuracy vs garrisons. In live version, where there are no viable anti-garrison tools that's necessary.
The point about the sniper might already be the case in WBP with the new PIATs, but that needs a lot of testing.
