is that possible? subscribe without tv package as i have the same requirement as yours?

movies, tv series, music, gaming, streaming netflix, youtube, browsing the web...... all these things download is all that matters.

heck even bit torrent you don't upload max. so i reckon 5 and 10mbps upload is good enough for torrent.
only time you upload is like when

1. adding attachment files to your email
2. uploading images to imgur.com
3. torrent upload (yes you have to upload in order to download, thats how it works)
4. live stream your game over twitch.tv
Only major problem i see here is for streamers. 5mbps may not be enough even for 720p, or barely :/

50mbps dl with 10mbps seems fine for me, even when i'm streaming.
PS: in my logs, my upload is quite high, almost comparable to my download bandwidth. but this is mostly due to torrent i suspect. O.... forgot to mention upload speed could be important if your an active torrent seeder on a private tracker. to build your ratio so you can download more, you need to upload more. so a higher upload speed would help in those situations.
