i will make it simple,
there are /party = where 4 can be in the same team
what about /reverse party = where i can pick 4 names that i don't want to be in the same team with.
if there are 3 of them in blue and 1 in red = i will be in red.
if there are 4 of them in blue and 0 in red = i will be in red
if there are 2 of them in blue and 2 in red = it will be random blue or red.
or if there are 4 teams, blue , green , red , purple. = the odds will be more to be in a Reverse party.
like /reverse party gabu kris r1 wylt.
you can make the max 2 or 3 names.
And it's should be before the match start to avoid any potential unfair advantage of it.
Conclusion :
1- it's an easy to implement feature and so useful for player.
2- there are a tangible need for it.
3- you can be in the opposite team of wylt always which means you can attack him in every match.
