Because they're putting up $100,000 dollars and want the best possible results and outcome from these events instead of lag tactics and Taco Bell wireless internet ruining the experience for others perhaps?
You're smarter than this
My point is that this would take time and money to implement, and I dont see why they would use those resources on something that a very very small portion of their playerbase would use.
You might have a case if those bad connections were winning ESL but they arent. It is almost always the same people so why would they feel forced to make this change? Online tournaments have lots of problems one of them being people's connections. They have no reason to see this as a big issue unless they start getting much less ESL participants/views. If that is already happening then they might be willing to do something but until then I wouldnt hold your breath.
Have you ever driven a car ?
Have you ever been on a Highway?
You ever see those signs that say minimum speed 40 mph?
Yea....
You apparently didn't read the end of my post. I get the idea and personally have no problem with it. I am merely pointing out the reasons why they might be hesitant to implement it. From NRS point of view this sounds like a bad business move. If they do it then great, but I just don't see it happening.
