Changing eny won't fix the fundamental issue of how people are choosing to play this game. ENY is no longer relevant when the horde can still overwhelm limited defenses, but at least it does keep the horde monkeys in lesser rides for a while until more numbers show up. ENY only limits some nice US bomb-trucks (38/47/51/F4/F6) generally has zero to brief effects on bombers or gvs (wirb and perk rides, shrug>
Here's another example of a situation that is present almost every morning:
Both bish and rooks are hitting knits, no bish/rook action and there won't be for several more hours (lafternoons EST). Knits won't have numbers to go on offense until later as well, so they basically "defend" vs the double teaming, losing bases until bish and rooks finally start going after each other, ignoring knits who then start rolling back bases mostly unopposed. As knits roll back those bases and more, bish and rooks start their own whining about double teaming.
The ultimate point I've been trying to express is that hordeing/fighting one side at a time just sets up a daisy chain cycle - you're either in the horde or fighting it.
If fights were more spread out between both/all flanks you might see both more fun fights and better tactical choices for the map strategy over the course of the day.
No, eagler, two sides will not help out, 3 is the way to somewhat balance things out - as long as players do so, which they're not, but 2 sides will only make it worse as the hordebois flock to one side.
