A way to have more map choice besides Summoner's Rift in Normals/Ranked, as well as map themes.

If you wanted to have 2 or more maps to choose from, I was thinking this is how the map could be chosen. Have a phase before champions are chosen/banned, about 10 seconds, where majority vote chooses the map.

If there's a tie, players get 5 more seconds to break the tie. If it ties again, a random map is chosen between the maps that tied (even if 3 or more maps tied the second time). A total of 15 seconds maximum, with many instances of only 10 seconds being added (because one map got the majority vote the first time) for the time we currently only do champion select and a ban phase, to add in the ability to decide what map is played on that match.

There's a chance with different map designs different champions would be meta, which could be a side benefit in terms of variety, and the ability for players who particularly like playing certain champions to feel like they're not making a sub-optimal pick (assuming the champion is better on some maps with certain team compositions than other champs).

It would also be nice if we could either individually choose different map themes that only we would see (all the other players would make their own choice for what they see, but the only differences between themes would be cosmetic), or to be able to vote on the theme for the selected map any time during the rest of champion select, meaning everyone would see the same theme, but we'd have some variety.
