So today I played a match with an Omen who keep smoking entrance when we attack. And we just kept dying. was he just trolling ? or there is a good reason to smoke entrance we didn't knew ?

it's just such a simple thing, I don't have the fastest internet in the world nor the most free time, I just wanna know how long do I have to wait before I can play and plan accordingly. I just don't understand how that's a problem.
