I would be against this because of how it was in the start with high ranking decks getting surrenders for wins, because no one wanted to face them and people wanted to keep their spins. If this happens, decks that are high ranking will just get farther and farther ahead because no one would play them to keep their rings.
As it is now surrendering is actually worse because you get 5 electrum back for voting when you lose.
I also agree with keeping surrender as it is, but I disagree with this tatement. Unlike in the start, people have tested and effective decks, like poisondials, splat, and whatever else is out at the moment. As long as you have common sense, you know that a win on a top 10 rank deck gets like 5 or 10 times the amount of electrum as say a rank 400 deck, so there is no reason to surrender to one of those without trying. They usually have low hp anyway and aren't that hard to beat.
As to changing the surrender option, I think of it as more a time saver, although I never use it. If you know that your going to lose, might as well save a couple hundred seconds of your time.
