u/Evilljustice

I have been running PBZ with Abaddon,hellbrute, Vashtorr, 2 defilers and 2 vindicators. Overall it has felt way too strong, I have played against guard, Ultramarines, blood angels and space wolves and won pretty much every match. Being able to lone op 18 with festering miasma, overwatch anything that twitches and kill it and then be able to point at anything in the shooting phase and just kill it is very strong. What are your opinions on the new defilers, do you think they will nerf them and if so when and how?
