Laying down smoke to organize a solid advance has long been a solid military tactic, however I notice in this game smoke grenades not only have really small plumes but also don’t last very long, making them nearly useless in a game that has such huge open wide spaces with enemies all over the place.
IMPROVEMENT: 2x plume time, 3x linger time
BALANCE: To balance this change I’d also suggest having the smoke be a little thinner so that if you’re in the (now larger) plume, you can see around you a bit better but if you’re on the edge of the plume you can’t see through very well to the other side. This would keep close quarters action in the smoke lively and also prevent interior spaces from being completely blocked out.
ALTERNATIVE TO LINGER TIME: Smoke could linger for the time it does now, but the grenade could just produce smoke for a longer duration. This would also allow an enemy to throw an active smoke grenade out of the area where it would continue to produce smoke elsewhere.
Nowadays, smoke bombs are very bad, and even have little effect. The experience of the attacker is also very bad, especially in the open area. So it is not hard to imagine why so many attackers will hide in the gray area as snipers.
Artillery smoke bombs also need to last longer and have better effect.
after all, no radio operator stops using artillery and bombing to use smoke bombs.
