Make other team visible right before blind or teambuilder match starts.
In draft both ranked and unranked, you're able to see the enemy team before you fight and that has a HUGE impact on the rune and mastery page you pick. Why aren't we allowed a 15-30 second window after everyone's locked in the other modes to do the same? The matches in these modes arguably aren't as serious, but why wouldn't you add such a serious piece of tactics to all matches in the game?
