There needs to be a "hey, life just happened and I have to dodge" function that doesn't penalize you but only has 3 uses or so. It could rebuild after every 100-200 games you play where you don't use it.
I know I should just not queue ranked and risk spoiling it for people. For the most part I do exactly that. I hardly ever play ranked games anymore. but ranked is my favorite part of this game, so sometimes when I am pretty sure she is going to be sleeping for awhile (say at 1am) I'll queue for a game or two. I'm pretty good about timeing it to make sure I wont have to leave and this is the first time I've ever actually had to drop ranked for it.
Anyway, just wanted to throw the idea out there. There is probably a good reason this doesn't exist, but I just had to dodge and throw my promotion series and I am frustrated.
