There's a way to suggest things. Even if you think the change wasn't a good one, you will not disrespect the staff members and write thing like "hire new ets". Next time your thread will be trashed.

I don't think it should be changed to 5 rounds. As someone who participated this event a lot, I always thought the event was too long. Some players camp, some players team up and some just run / waste time because they are simply trying to survive instead of throwing nades at others. The winners were usually the same ones and at least half of the users left after the 3rd round.
