Meh, as I said, its just my preference and will obviously back adding it as a tier for laddering. My thought process on the predicting is that its still possible with no preview. Its just a lot harder as instead of knowing the 5 possibilities of the switch, you have 717 (well, obviously not that many but you get the gist)...
Again, just my opinion on it I am always of the camp: more tiers are better and agree that it can be a good ladder tier.
