Environmental effects

The announcement of Kelvin got me thinking. Do you guys think there will/should be environmental effects from the maps? Water that slows you, poisonous gas, frozen tundra, a sun that hurts like the geth map from mass effect 2. I think that could add some seriously fun twists to the battle

When fighting a certain mid-boss there is a moment a room fills with poisonous gas. This did affect you a little bit but not too much.
