We should be informed about the map side dedicated to us throughout the whole lobby

I say this is particularly important with the new runes that came into play. I dont know if anyone shares same impression that I do, but recently I wanted to make decision on whether to take waterwalking or scorch, based on the side of the map I play in. I selected jungle and thought of taking waterwalking if I wanted to gank toplane once im done with both of my buffs. For example, red side allows to take a plant into baron pit and then path straight into pushing enemy top laner. If i knew this wasn't an option for me because im blue side, I would have for example thought of taking scorch, and going mid straight after im done with my red buff.

As it is right now, I believe you are only given a information at the very start of the lobby, where you have a highlighted image of your side on the minimap that appears briefly before banning.
