Honestly i think they are smart as F**K here.
They launch with 2 PVP Servers and gets LOADS of attention, they get people talking about it EVERYWHERE.
There is no such thing as bad publicity, this is Actizzards last hope to get a good cashflow from subs again and they have to get it right, they have spent huge resources on getting the game right and it will be good from what I´ve seen.
They will probably add more servers and as stated before it will be both free transfers and “new” servers as well after a while.
But what everyone needs to realize is that the hype is real, ALOT of people have been waiting for this and blizzard knows this, they are smart and they arent gonna screw you over in the end. I think the whole topic around layering is just the reality as of today, bringing back crashing servers wont be fun for anyone and you will still be able to connect to people.
Give blizzard a chance, most of you are atm crying about a product not even on the market.
