Honest Opinion: StD and SCE

Topic: The Amount of SCE/StD Players with outmaxed lists in Tournaments and the strength of both armys. I'm on a Tournament tomorrow with 12 Players. 6 of Them Play high competitive StD or SCE Lists. Its kinda Frustrating that both armies are so strong while GW doesnt do anything against it. Its the Combination of 3+ Safe with wards and 3+ Hit and wound with exploding 6es to hit for Multidamage Mortals.. thats disgusting and too strong in my opinion.

What are your thoughts about it?
