well, let me put it this way.
in Australia, during the games, there are about 10 users who come into chat and are online and watch the games, and probably another 30 that arent in chat. so thats 40 users.
and those 40 are never the same. it varies a lot, but lets just say its the same 40 users.
Now - the aussie community has around 427 active teams. so thats only 10% that come online during the games.
so if you introduce live substituion, only about 10% of people will use it.
So the suggestion only caters for 10% of the BB population. Is that fair do you think?
The game is a management game, not a live interaction game, there are other games that cater for that ....(. Im about to buy NBA 2k14, to play live interaction. )
and basically, this suggestion has been suggested for abouot the last 4 years, since Buzzerbeater ever began. if you search the suggestion forum's you will see it suggested hundreds of times and it has never been done and never will be. This game just isnt meant for live interaction.
