Considering my local group of player,
we have the feeling that empire/orc are the strongest factions and chaos/dwarf the weakest factions (nevertheless it´s just a feeling).
In particular, orc rush or agro-control is unstoppable when the opponent try to develop his quest and his kingdom phase,
of course due to the vomit/ and the big orc...
But if the orc player´s opponent try to blitz, even if the deck is not built for that (an standard dwrf deck for example), the orc faction can sometimes be defeat.
I just want to know if you have the same feeling: is it absolutely necessary to play blitz against an orc deck ?
