Very often, when you group with strangers, you don't know who you're going to play with. It can quickly take a long time to look at the dotabuff one by one. It would be great to be able to have the basic information of people who are in the same group as us in the game menu. For example: the number of recent games, previous scores and favorite positions.
This must be complicated, because there is no request that is sent to the server that creates an instance. But one can imagine a quick search from dota plus.
I don't know if I'm very clear, I'm making an example: I decide to join a group, I don't know 3 players. Thanks to the extra stuff, I can quickly see some basic information. That way, I know if they're big dota players or not, what position he plays, etc.
