These polls are certainly not scientific and the results could be interpreted in different ways. Poll design is actually quite difficult.
Fridge and Summer both show examples of how you could combine multiple poll options and then argue that the sum outweighs the other options. In theory this could be correct, however the data does not conclusively prove the theory. Only further polls could.
There's all sorts of examples that you could argue should be combined. You could even combine Final Earth and Heavy Earth's numbers since they both contain Paraguay. 72 voters voted for maps with Paraguay versus 54 that voted for maps without it, so clearly Paraguay is very important to voters, right?
Could that be true? Yes, it could. However, the data doesn't conclusively show whether voters voted for those maps based on Paraguay or based on some other factor. There's no way to be sure based on this poll data.
I present this as a silly example to show why combining poll options is a guessing game. You have to try to guess why someone voted for what they did.
One option that was never even considered that should be: there should be extra time given for picks.
You should read the actual poll. This was considered -- it was on the poll!
RT ladder being changed to 3 minute boot
It's not being changed to 3 minute boot. It's being changed to 3 minute boot with 5 minutes initial bank, meaning that you can actually take 8 minutes for a turn if you want. It's possible you knew that and were just omitting it, but everyone is focused on the 3 minute thing so it might be easy to miss that.
