TLDR:
There are two basic ways to gain an advantage over a same range opponent in a long distance. One is to have cover. The other is to have the high ground. Snipe on Mincemeat is clever in that it makes players choose one. A backliner stationed there can right-side peak OR they get elevation on the left. But they can't have both. Dumber maps combine right side peek and elevation in the same spot.
Mincemeat also makes the correct call to have the distance between the two sniping areas be larger than the distance covered by the longest range weapon in the game. So you don't get a situation where games are solely won by sniper duels. Snipers actually rely on their teammates to make plays.
Then there's how thin that stripe of area around snipe is. The best way to neutralize long range weapons dug in on high ground? Get underneath them with a blaster or slosher. All that range can't shot over walls. And a sniper on Mincemeat can't back up very far until their back is against the wall. Where the floor is uninkable, so no hiding and no regenerating health or ammo.
The latter, at the same time and elegantly so, works in favor of the sniper's team and against the blasting or sloshing aggressors should the sniper's team get wiped out. Those blasters and sloshers can press their advantage, but because the floor underneath where the respawning team comes in is not inkable, that hinders sharking and means enemies have to move around in the open to regain ink where they can be shot from above.
We'll not speak about why those smart design decisions are let down by other parts of the map.
In conclusion, the trucks are awesome!
