I have like 1mbps atm...my plan states 2-3 mbps but I think it's because I'm in a 3G neighborhood or something...can you tell me what I need for League of Legends, like 2-3 MBPS? I'd think that's what would take...
1mbps is probably fine ofr LoL, but your ping may be another issue. Have you tried just playing to see what the experience is like? If you are going to have issues its probably going to be from latency not bandwidth.
