Do unique heroes become available in the GC's with latest patch or is it a treat that comes with the Mega Pack?
Furthermore, I own all the GC's save for the western ones from 42-45. Is there any sense in purchasing the Mega Pack instead of buying the last mentioned western GC's separately, should I desire to play the whole series?

Hello freud, the Mega Pack is just a single installer for all the GC's, a single package for convenience. The latest patch for the game will upgrade your existing GC's with the same features as in the Mega Pack.

It might make sense to get the Mega Pack if you want to add the last three GC's to your game. If you already have some or all GC content you can get a big discount on the Mega Pack, up to 70%. See this topic viewtopic.php?f=121&t=41949#p395238

The three West GC's would come to nearly 15 euro, and the MegaPack is almost 33 euro without discount, but since you already own the first seven GC's you could get up to a 70% discount, so you would pay less for the Mega Pack than for the three West GC, if I'm not mistaken. (check carefully, and don't forget to register all your serials, see the thread I posted for the details).

That is a neat discount indeed. Thank you for illuminating me on the subject.
