then there'd be no masteries or runes. or summoner spells even.

I keep waiting for someone to come up with a ban list along the lines of what we used to have with this games predecessor for queue dodgers. I don't know what happened to that banlist program that warned you when a leaver joined the game you were hosting.

I think this is a good idea. No runes/masteries + random summoner spells. Gogo!

I think this should be made reality!

The much easier solution would be to shorten the timer before going to the loading screen to 15 seconds. So you'd have enough time to choose your masteries and runes, although just barely and be less annoyed if someone dodges just before the game starts.

The countdown is much too long. I think 20 seconds is enough. You really shouldn't be screwing around with your masteries that much; there are enough pages available that you can set up pretty specific pages for any champ you might get.
