We have two original factions that are designed around combined arms, which means they need to support their weaker infantry with support units. Removing snipers would mean these two factions are either left with going back to mgs and mortars or spamming infantry. Is that the direction we want to go?
That does not follow at all.
Infact, the opposite is true since ostheer played for about 2 years without a sniper since it's hp was only 42. Ostheer is not known for mgspam. Sov t1 is also not known for combined arms. OkW and USF are also not known for spamming support weapons.
Snipers are not needed for combined arms, they ruin it infact, when they hardcounter both infantry and support weapons.
We don't "need" snipers, but if there's an opportunity for us to include a unit that works well in combination with other units rewarding a diverse troop composition then i don't see why having that extra unit would be bad.
But it doesn't reward troop composition, all you need is infantry with snares and you're good to go.
Everything else gets hardcountered by the sniper.
In a game about veterancy, unit retention, RNG, positioning, flanking and cover, a unit that ignores it all (snipers) is broken.
