This last weekend I was hit with ENY very often. At one point it was up around 22 and it was not really much fun.
ENY is a blunt instrument and it will never be able to account for local concentrations of force outnumbering the high numbered side.
I personally don't care for ENY and I suspect it does more harm than good when coupled with low player numbers and long side switch times but I do not see it getting changed so don't dwell on it too much. If it becomes an issue for me I log off and go do something else but that does not happen very often as I tend to change to the smaller sides and my game session is usually done before ENY hits that low side.
