Here is a post I just made on B&C. You can follow the conversation here.
"Now, we all know some of the panic D weapons have caused. I
personally think they have a place to deal with things like:
screamerstars, T10 MCs, Riptide spam, Serpent spam etc. However I can
see how adversely these weapons can affect the more casual side of the
game should you want to use a SHV in a tournament at a FLGS where you
know there aren't all WAAC players that power-game. So how do we tone
them down to be able to take down the power lists that abuse the system
while still not steamrolling a more casual player.
Just making them S10 AP1 Ignores cover will still splat most thing but screamerstars and riptide spam will laugh it off.
Perhaps a slight alteration to D weapons and how they affect saves.
Now lets say that D weapons don't automatically ignore all saves, but
only do so on a 5+. This keeps their ability to deal with screamerstars
while keep other more casual lists viable. More difficult sure, but
significantly more possible.
Edit: Perhaps they reduce invul and cover saves to max of 5+? Gets rid of system abuse builds but retains a more casual friendly aspect.
