Maybe we should see the ork problem from another perspective. Orks have mainly problems with Eldar and Chaos now.
Eldar because of the hated Warpspiders....which are way too effective versus light infantry in the hands of an experienced player. And since most of the ork army consists of light infantry Orks wont a chance (and also makes game versus Eldar truly boring and unfunny as Ork)...the answer in 1.2 was the Trak but thats taken out now, nothing left to do.
Chaos with the new defiler...with his fixed autocannon he chewes through your units...especially massed (probably a problem in 3v3 or 4v4 since there usually larger armys get built beofre the first fights)
Why dont we fix these 2 units to normal combat strength before we change anything on orks and see how they fare then ?
Maybe make WS do less damage and make them a little cheaper for that
And give the autocannon less damage
this changes should help orks a lot
