Nitrogensports tends to have a lot of good esports lines, especially for obscure games in Asia and Europe. The obscure games are where the real money is at, since the lines are often soft. SEA Dota, EU csgo, and Korean/Chinese LoL is where money is to be made.
In my opinion about your statement in DotA, SEA low to mid tier teams are extremely risky to rely to bet with, but at least we can see more Asian teams making a superb performance this year.
I guess the SEA now is getting into the top already step by step and I can say that SEA teams are already improving. It is a matter of practice.
I am really impressed for the performances of different SEA teams for this year, and after the fall shuffle.
For sure that we are going to expect more in the future.
