..... No.... its not, not really...
My most consistent opponent is a Necron player, and though he does not bring the 3x6 + tons of flyers Necron cheese list, he always includes at least 1x3 or 2x3 of them to force me to spread my fire. Another friend tends to bring one unit of 6 with charriots so i can say, that the Wraiths are something i can always expect to see.
there is only one answer to Wraith squads that can bypass that invul save and thats TONS of dakka. Just treat them as you would any Terminator styled units. They roll a 3+ invul, so you just have to force as many wounds as possible to make him roll those 1 and 2. Mass Fire Warrior fire and/or focused attention from HYMP Broadsides / Missile C. suits, tends to rip them rather nicely.
