As of Patch 6.2, lapsed accounts may use their Battle Tag from their Friends List.They may whisper their Battle Tag friends across games but will be unable to invite them into a group.Depending on the profession, lapsed accounts will be unable to create some mid to higher skill items from their professions without an active subscription.They may learn new recipes given the appropriate skill level but if these recipes are mid or higher level (about at 60 skill level) they may not create them.Once you upgrade to a full account, you will never be reverted to a trial account with that account.You can, of course, create more trial accounts that have the same limitations, but you'd have to upgrade those ones too to get the full range of gameplay. Blizzard announced today that they're completely revamping their trial account system .
You will no longer be able to play the sub-20 "freebie game" on that account, as that account is no longer flagged as a trial account.
