Can't run Technic w/o a copy of base minecraft?

[gigaus]

So I haven't played on Technic for a long while, almost a year now, and last time I played on it I could log in without being connected to the internet, just so long as I had a minecraft account. It was great, because I could take it with me on trips when I wouldn't have internet. 

Now, since I don't have a Mojang account after the migration, mostly because they refuse to recognize that I ever bought minecraft, had a copy, and all that jazz, I can't log into technic; No copy of minecraft attached to this account or some such....And when I tested trying this without a connection on a friend's laptop who did have a migrated account, surprise, it didn't work. When did this happen and why? I'm mostly curious because I need to know if this is just a screw up-- yes, this is a screw up-- on Technic's part, or if every platform is like this now.

You will need to log in once with a valid account while connected to the internet in order to cache your credentials. Been that way for quite some time.
