Invasion mode is still a bad idea even if you give it a different name.
Have you ever played against an NPC that has a bow/crossbow/gun in an invasion mode?
Yeah they're fucking cheaters with their bloody headshots.
It's true that the bots will basically destroy any defenders with their laser accurate shots.
WWII: China Battlefield's Last Man Standing mode is quite fun despite the laser shots. Bot accuracy can also be reduced. That being said, there are currently no plans for invasion mode but it is a possibility for the future.
Yeah, just make sure that bot accuracy is highly reduced to N&S levels. Rifles are accurate, but when you're trudging through the fields and not having your weapon rested, you're not going to start plinking people off half a km away.
I would even suggest rifles be as accurate as B&I to account for human error.
