I'm not sure but I think its possible to play DOTA in high speed among the IS PROS users. in Garen we are limited to our internet speed. But if we (IS PROS users) can manage to play in LAN that will be a lag free and there will be minimum latency. We can download big files with p2p files so I think we also can play online games like DOTA, CS, COD etc very easily.
We should schedule a time and give it a try. We can use yahoo/msn to communicate during the process.
my yahoo add is [email protected]. I'm a DOTA fan. Hope there are more dota fan like me here. Please let me know what you think about the idea.
