I'll be honest with you here.
You're going to experience
true skill. MD/VA is overall the strongest region in the country. I've yet to have an easy around after the first in singles or teams, and I usually just roll over everyone in NJ and get top 3 easily. Playing in MD/VA is a nice shock after playing in <insert clearly inferior region here>.
That being said, I will be very surprised if you do well given how incredible that region is.
Also, bear in mind that I compete with all of them as a peer and that I have beaten Boss, Candy, NEO, Chillin, and Forte in singles, as well as two top OOS players AlphaZealot and Atomsk that will be there. And I've beaten...pretty much all of them but Azen and Chillin in teams because they lost before getting to us.
