From what little I've gathered, you've got to pay close attention to when he activates trait. With it active, he beats a lot of NW's pressure. Just back off and harass him with ground blast/spark or wingdings. His 3 and strings have crazy range and priority when trait's active, but aren't nearly as scary when it's not. When it wears off, go in and do damage.
If you're playing the long range game when his trait's up, it's only a matter of time until they teleport to get in. Block high (the uppercut hits mid and the kick hits high, iirc) and punish accordingly.
Be wary of one of his projectiles, it may be unblockable. I kept getting hit with it on wakeup, even though I was blocking (tried high and low). Maybe lag? Dunno......
