Not too sure about this, but wouldn't the EC prove more of a gambler aspect if it was to be used in the early rounds (1-3)?
It was quite easy to see when teams got eliminated, to predict it if they went out in a few rounds, or the next round or something.
Point is, I don't think many people predicted water or earth to be going this well at this point, and entropy to be going not as good (not having a go, just trends I have observed).
Maybe an unpopular opinion, but just my view on the EC
All in the spirit of constructive criticism.
