At 6mbps? Tons of consumers in the US get even less...
Between two TVs using Netflix (usually no more than one at a time, but frequently) and me playing online games the connection becomes about useless.
Ping times shoot up past 1000ms making online gaming impossible, downloads are obviously slow (and interfere with Netflix streaming), and there's frequent connection bugs (stalls for 2-5s seemingly randomly).
Only other "Real" choice is Comcast, but I'm very reluctant due to their behavior and potential of implementing low caps. (Not currently in WA state)
4G isn't an option because data caps, sat (Which I used previously where I lived before) has extremely high latency and low caps (Obviously no multiplayer gaming there either), and of course nobody wants to deal with dialup in 2015.
