My 12 year old brother has a season ticket. When I was home over break I got to see some of the 1080p+, and I have to say that it is the best looking live stream I have ever seen. The colours are so crisp and the lighting is fantastic. I have failed to see a better looking live stream.
The games I have seen are really good. A lot of good macro games, a handful or tense and awesome games where 1 player all-ins, and everything in between. The games make the tournament, and NASLS2 delivers with a wide range of games.
A lot of really interesting builds are showcased. The best, and most recent example in my opinion was Jinro vs Sjow: http://nasl.tv/Videos/week-3-division-3-jinro-vs-sjow
I feel like every week I see builds that I can try on ladder, or at least me think about the state of the metagame (I hate that word).
The website is sweet. I love seeing the standings, upcoming matches, even being able to schedule my favorite upcoming matches in google calender. Little things make the website shine.
The players, with the whole division dynamic, make a cool storyline if you have certain favorite players. I am rooting for iNkA personally, and I like to be able to see all their upcoming games. Creates a sense of drama.
The intro graphics are out of this world. Really awesome. Also excellent production on interviews, top 10 plays, and match breakdowns.
I am quite glad that I spent 25 bucks on this season. Have not regretted it at all and I would highly recommend others to buy a ticket.
