There was some speculation why Blitz team was in EU practicing and bootcamping especially when they are a NA organisation. However ending all speculation Blitz has clarified that he has move to EU along with his team simply cause every other team is in EU. It is hard to find scrim partners in NA and as such they made the decision to shift to EU temporarily.
