Neutral. I'd love to have it but it would probably cause a decent amount of lag

+1 All for it if it doesn't cause lag. But bro. Will this be Minecraft?

+1 would like it, but as said by ever one else it most likely will some how cause lag

-1. Sniper glint in the dark? Hell naw

+1 More use for the flashlight

+1
Would be nice but will probably cause lag somehow. Cross will also be pretty powerful whenever it is dark.

+1 It would give fresh air for the server, also the sniper glints should be very reduced in the night since there isn't too much sun to reflect

Neutral

It would be really cool, but you can’t have shit in source engine games, i can see, that there will be either ton of lag or shit ton of work behind it.

+1 i like the idea, but lag would be a problem

There's already an addon in the works that does just this and more for (allegedly) little to no performance impact and very customizable. StormFox2.

I would wait for this addon to come out (in the year 2035) before considering things like this.
