I voted yes, but that's merely because i hardly use them or forget them at all.
It might be good to ban them on the 24/7 server, as overgrown is, imo, not really a snipermap.
I use the clays only to cover an entrance, while i am on top or in a high building, overlooking a large part of the map using G3.
Not very effective in an open field, protecting my behind, while sniping.. wich i rarely do...
I understand it's a perk one can use, and might come in handy at times, but i wouldn't miss em.
But also understand that some love to use them as backup..?
So in all fairness, i don't mind them, but don't care for them either.
It's part of the game and inventory...
Cheers Rob.
