I don't even know how to give a serious comment on that...
What's not to comment on? The ENY system is designed around the notion that three sides will be fighting each other. if two sides gang up on a third it breaks down hopelessly. For example, normally, if you had 40 rooks vs. 30 bish vs. 20 nits, the rooks would have a high ENY; if 10 of them switch to nits, the ENY goes away but now you have equal numbers fighting each other. However, if it's 40 rooks and 20 nits all ganging 30 bish, 10 rooks can switch to nits and get rid of ENY while still having 2-1 odds all across the map.
And 2-1 across the map is even worse than it sounds, because having those numbers and flying in hordes on a small map means it's easy to beat down resistance and cap fields, so the "fighting" becomes a giant across-the-map vulchfest. Of course experienced players and squads will fly in from other fields or otherwise avoid getting vulched over and over, but that's a minority of players, and it becomes a steep uphill fight against odds, which gets old after several nights.
The worst night for this recently was Thursday; at one point there were 80 nits and rooks ganging up on 30 bish with no ENY (or ENY under 5, which is the same thing) and not one single flashing base or dar bar on the whole rook-nit front. That's just ridiculous. If we're going to have ENY, then there's no excuse for having 2.67:1 odds with no ENY.
Another aspect of this problem is that even though it theoretically evens out over time, each side getting it's turn "in the barrel," the problem is, that assumes that having 2-1 odds on your own side is as fun as being outnumbered 2-1 is unfun, which I do not find to be true.
ENY is very, very broken because of this central conceptual flaw, the built-in assumption that all three sides will fight each other.
