Top 8 NA vs #1 in the world cause of 1 player... That shows you his worth. The fact that they are as good as they are without a coach, also goes to show just how valuable Shahz is. Just think about all of the comps that Sentinels have played with that other teams starting picking up after Sen played with that comp and the fact that Sen have stayed on top of NA for so long, despite the changing meta and even a roster change. Not to mention the fact that he's probably the most individually skilled, top tier IGL in the world. Not to mention the fact that, at Iceland, he was one of the best performers.
