First at ALL, Congrats to all the placers but specifically to OMEGA who really did his best effort to be ready to tournaments; he spend a lot of hours training and watching matches and studying the game, so no matter the character he was ready and prepared...
Second, the commentary was good all the way, Bibulus, Hates, Jaxel, etc did a good job trying to explain the game and its new mechanics; Filtierich do an awesome job within the HYPE department, while Markman did really good analysis and explanations all the way... Markman said: "Omega is my favorite to win, he was really consistent since his first match in knowledge and technique" and guess WHAT? Omega won and Markman said first.
In third topic, tiers are not game related this time; is "training relate", a lot of people use Leixia and Natsu but most of the players attending were ready to face those characters; only perfect timing, distance management, to take every chance at is fullest, and know how to play in every stage/situation/style is the key to win.
Nightmare is not top tier... is solid mid... as Siegfried, Astaroth, Xiba, Patroklos, Pyrra, Yoshi, Cervantes, Ivy, Tira, Leixia, Raphael, Voldo, etc etc etc...
