Hello Silviu,
once again; thanks for taking the time to respond. Man, Codeweavers should hire you, considering the amount of time you spend posting and testing things around here.
Anyway, I tested Crossover on two other laptops today. Both of them had the same issue - missing libs and bugged install via USC. It's just extremly strange, because I can install other things via .deb without an issue. The only app that I have had issues with is Crossover. Also, Ubuntu is one of the officially supported plattforms that Codeweavers supports, yet these issues have been "bugging" us since Ubuntu 12.04. I can understand these things happening on an unsupported OS, like openSUSE, but not on a supported plattform.
After I installed Crossover yesterday, I tried to install WoW for my gf, but the installation would just hang when trying to install Visual Studio 2005/2008. Before that I was playing around with what I wrote in my previous post (= trying to find out what went wrong again). At this point I uninstalled Crossover to test something else...
Out of curiosity, I downloaded and installed vanilla Wine (1.7.19) and PoL (newest version) seperately, just so I can compare it to the current state of Crossover. Before I installed them via USC, I added the ppa-repository for both projects via USC. What can I say? Both apps installed just fine and both install, launch and run WoW out-of-the-box. Wine even updated itself via Ubuntu-Updates yesterday - and all I had to do is click once or twice on one or two buttons. PoL grabbed updates by itself too, offering me updated scripts and the newest version of Wine (1.7.20). Both projects support several Linux distros and offer an easy way to add a ppa, which will then update their software in an easy and fully automated way.
And that's not even talking about the lib issues Crossover has had. I understand some ppl don't want the "unessesary" bloat that comes with that decision. The alternative: If you can't offer all the libs in the default Crossover installation, at least make it optional either before, during or after the installation via a simple checkbox or dropdown-menu. That would make life so much easier.
Edit - deleted previous post: Nevermind what I wrote here. I was just a bit frustrated but after comparing and testing a bit with all three "products", I have come to the conclusion that Crossover can be a pain to deal with in terms of installation and updates, but both performance (for example, performance enhanced graphics created by Stefan Dösinger) and ease of use are still superior to anything else out there - but only after sucessfully installing everything correctly. My main concern remains unchanged though; I'd still like to see the issues fixed that have been pestering us since Ubuntu 12.04.
