Subtitle support was already great back in $a_date_long_ago_in_computer_years. Dunno what 2.0 improves on, fluff support was already pretty good, probably it's about doing that on soft subs.

The issue is about cheating, Blizzard cannot verify if during your offline quests you didn't cheat, sou you can't go online with the same character and play with other players under the same rules.
The answer is simple, when you want to play offline, you can either start anew, or load a copy of your online character in cache in your computer. The Battle.net version of the character and its progress will remain frozen. When you choose to play online, you just continue with this online version; offline "tainted" characters won't ever be able to play in Battle.net.
This way you can have multiple "saved games" offline.
