Matchmaking does not start in party of 3+ if too many duplicate hero selections

[ms.timafeya]

Description:
When queuing for a match with more than 2 players in a party, matchmaking does not start after hero selection.
We spent around 30 minutes trying to understand why the queue was not progressing, and there is currently no in-game explanation or warning about the issue.
After testing different scenarios, we concluded that the problem appears to be related to hero selection.

Steps to Reproduce:
Create a party with 3 or more players
In hero selection, choose multiple overlapping / identical heroes within the party
Attempt to start matchmaking

Expected Result:
Matchmaking should either:
start normally, or display a clear notification explaining the issue

Actual Result:
Matchmaking does not begin, and no message or warning is shown. Players are left without feedback and no indication of what needs to be changed.

If anyone is stuck with matchmaking not starting in a 3+ party — try selecting more different heroes within your group.

We had too many overlapping picks, and once we spread them out, the queue started immediately.

Hopefully this saves someone some time
