I wouldn't say the Primordial cycle was specifically bad for EDH, but I will comment that pretty much anytime WotC designs a card or cycle specifically for EDH, it seems like its a hit or miss, with no middle ground. And it's usually a horrible, horrible miss. All my opinion, obviously.
To be frank I agree with you lots. Many of the specific commander designed cards have tend to make the format more unfun.
