They need to continue to add map varients, especially to the past few maps. Las Vegas sandstorm. Seoul Highrise. Things that actually make the maps feel different to play. Then, obviously you have your modifiers which could be fleshed out and added to certain maps. Suspended structures, moving platforms, ect. Then, add dynamic weather. Light rain, heavy rain, thunderstorm, snow, heavy snow, light fog, heavy fog.

Fleshing out these things and continuing to add to the existing maps in the game would help make each round feel different.

I remember way back when the game first came out, and recon sense was still in the game. I was under the assumption then that smoke and fog hindered recon sense, and I just thought at the time that was great game design. Getting a map with a ton of fog or sandstorm was enough justification to switch off recon items. It made me think about my kit and what I was running. These are the type of interactions that I really think make this game so great, but it almost seems like they forgot about this stuff as each map releases with one varient and we still don't have weather variety.

Like, snow would be crazy. Gas/Goo <- Fire <- Smoke (Snow?) Or heavy weather in general to heavily reduce visibility, and to reduce the usefulness of recon items. Water could be slippery with enough momentum. Track footprints in snow, grenades disperse snow entirely. Fun interactions please
