Here are the brackets, these have already been discussed so they are not subject to change so don't bother moaning as these won't be changing.
Brackets aren't randomised?
No of course not, any decent host knows that you make the brackets semi-biased to make for a better and more fair tournament so that one group is not op and others shit. Not just in NWWC, any 5v5, etc.
P.S
The start date for these matches will be the 23rd of April and you will have two weeks to complete all your matches in the group stage (deadline 7th of May).
