I find myself too often leaving the lobby by default or even having client crashing. Sometimes, I even close the client.exe myself to increase FPS in game.
Please consider allowing us to Honor someone after leaving post-game lobby. I can think of few reasons why you shouldn't do that, but I will provide what I think are good solutions:
1) What's the value of honor if you give it few hours/days after the game? It's lower. You are not under the effect of that particular game anymore.
Solution: add a small time limit, i.e. 15 minutes.
2) If people saw they were honored, they would feel "obligated" to honor their teammates/opponents back even if they didn't know who it was.
Solution: Let received honor register AFTER the time frame for giving honor. For example, if your time limit to give honor is 15 minutes, let any honor you received register 16 minutes after the game.
I can't think of any other potential abuse cases atm.
