The consistency is a good thing from my perspective. Last game I was playing against someone who played an early Ruunin, the Relentless. It’s insanely powerfull in that setting but since I managed to make a better deck overall I was able to win regardless.
With less consistency it’s more about the few big choices instead of the mass of little ones.
I enjoy it when I play it, but I do agree that it would be a lot more exciting and have more appeal to start a run if it were mixed up a bit more, however I don’t think simply reducing the number of options per pick would improve things.
A lot of people prefer to play Green because the current Green cardpool is very consistent; pretty much every Green card works in a standard mid-range Green deck, so you can’t really go very wrong, whereas if you try to draft a 3-Wishes deck… you may be disappointed.
