1 vs 1 room for 10 ppl. PLZ DEVS READ THIS)

Guys can you add this innovate thing to your games? I guess it will be interesting, not just 1v1 room but make a room for 10 players 5 each team but only with 1 vs 1 rules.
For example make a door that allows only one person to pass through.

I see it that way: you are joining the match and spawn into cage with 5 members opposite team also got 5 members. Game starts when u have 3 members each team when door is open only one player can pass it through from each side. Then they have 1v1 battle winner stays and other guy enters.

Only one problem i see is a lag bug (like a ctf ones when u can pass on stage when door is not appeared, i don't know if it still available to perform because i am not using dance anymore)

P/S This will make tournaments more easy and i really never saw this in any other mmorpg IMHO
