the team alredy plays worst then with normal, and to play TIE/Normal/CT is an key element in Buzzerbeater which gives pretty much and funny tactical experience.
Porbadly is ain't relaisitc, if you say play tie to professional player, they maybe play with half energie so that they don't get injured, but won't be better in next game ... But here it's a game and the main propose should be fun, and i think tie is fun.
