The proposed system is 100% better that what we have currently. You might not like the fact that one team picks their opponent but everything else is far superior. On the whole, we're way better off under the new proposed format.
It is way better, and you are gonna get 2 eastern teams in pretty much every year anyway, all 5 teams in west can't be better than the second best team in east, and if it is possible which I doubt would be as rare as a Rider Grey Cup, the only difference is the 2nd east team may not be hosting...and oh well too bad so sad
