You might have a good connection, but what about everyone else who has a worse one than you? That's a bit selfish right there, if you ask me. I HAVE A GOOD CONNECTION SO I WON'T EXPERIENCE LAG! Yeah, good for you. One person's good connection does not equate an entire nation's connection. I admit to not knowing much about network speeds, but what you said struck me as selfish and rude. I'm sorry.
Regardless of that, as OBJECTION MAN stated, network speeds aren't good enough throughout the country in order for a dedicated server to host 50+ players at a playable speed. And if they limited the players per server to say, 25, or even 10, then there'd be too many servers. There's also the cost of maintaining the servers. If not enough people are willing to play a game that would run slowly on their computer and/or pay a monthly fee, then maintaining the servers might not be feasible. It also comes down to the economics of bringing it here. You may be excited for it; not many others in the states are.
And if you don't know a lot about network speeds, don't call the point of someone who does invalid. It's a lot more valid than yours.
