They are weak in their micro and macro. The NE race itself is STRONG. The proof is NO NE player dominates the mirror race. So they are weak not because they cannot beat players in other races, just because they cannot beat other players in the SAME NE race.
The proof that the NE race is strong is that even if you just rank 4th in NE, you can still attend games with 16 places and often go into the play-off stage with 8 places! I cannot imagine the ranking 4th UD player or even ranking 3rd Human player (see my list below) can join such games, as there are players in the Random race. And the chance for ranking 3rd UD player and ranking even 2nd Human player is small to go into the play-offs.
Moon, Lawleit, Kaho, colorful, who can usually beat the other three? No one knows.
Happy vs 120, Lyn vs Focus, Fortitute vs Sok, it is safe to say the former ones have 80% chance to beat the other in the SAME race in all the recent PATCHES.
(Of course you can add Labyraith, xlord, Fly, soin, Hawk, blade etc to this list to make up four players in each race, but to be honest their chance to challenge the dominating race players is much lower.)
Happy, Lyn, Fortitute present their better micro/macro in such games, so they deserved the current Top 3 places.
