If you have older games on disc that are available to purchase on Origin, call their tech support. I got bf2, bf2192 or whatever number it is, and C&C3 converted, and each one came with all dlc, despite me not having it in the first place.
I'm not a fan of having more than one distribution platform, but EA converting my games with little hassle was nice. I realize it's to entice me into using their platform more, which it doesn't.
Anyway, on-subject: the lack of discs is ONLY an issue if EA uses it as a way to keep prices high. No retailers trying to dump excess stock means no pricing competition when they have the ONLY place to get their games. Despite their poor track record, they occasionally do have a good game here and there still. If they continue their sales as they've been doing, I don't see the disc-less EA as a bad thing.
