The problem with boyz being the best choice is that you get really predictable. A good army needs variety in usefull units so your tactic isn't super obvious.
With beakie armies you got a million ways to deal with most things. That opens up the field for many different tactics. And in the end a good middle ground between shooting and melee is more viable than being stuck to the green tide tactic - where all you can do is move forward and attack as far as decision making goes.
Even if they still want to go for the mass approach they need to drop the points for the ultra situational units like Burnaz and Flash Gitz. Hell even Lootaz could be 1 or 2 points less per modell.
All in all it's hard to tell where they should go with orks since there is many way to make things viable. But in the end I think an army needs a decent number of viable units/choices to make sense in the first place.
