Did you notice..

That most battles are during the day and afternoon on all maps?
Why not have night time battles. Some with a moon and some that are almost pitch black. Using the shadows for cover other than a big rock.

Of course need new toys too Stealth, thermal vision, night vision perks or old fashioned high beam lights.
Ex.
Stealth is good an all but one fatal flaw - the movement of the water technically if you move you can be seen if don't move your invisible.

Thermal vision probably one of the best since all boats produce heat.

Night vision it's okay but unpredictable, that has weaknesses you might have your target but when fired you miss it... Night vision greatest enemy is high beam lights blinding you for a few seconds.

 

Another great idea for an update, at this point I'm literally waiting for something new to play the game again. Sooner or later the devs will whip up something grand and we'll all be back in business.
The Foundry map was called the night time map, it's not pitch back and you can see everyone just fine, but that's what it was called. Also the Crash and Burn mal is kinda night time as well.

 

But there is no challenge if you can see your target at night usually irl it's either radar or sonar. For ex. Your chasing your target then you lose sight of target only to have target behind you instead. But, if you were a two steps ahead of your target you would plant mines behind you and since it's dark well you get the picture. Most ppl rely on the targeting what if it was gone will be more challenging

 

I agree there is no extra challenge, it just looks different all these ideas could be quite interesting if implemented. I would love to play a game without target help from the game, it would make me focus more on my skill.
