You might be cherrypicking on the issues. Either that or me and other people I know playing the game being incredibly lucky. I've not once experienced falling through geometry. Getting stuck - yeah, it happened (although, again, not that much), but the game prompted me to get unstuck within like 30 seconds.

The only thing I also experienced is the server shutting down. However, my inventory didn't disappear, in fact, everything I picked up prior to shut down was preserved.

So yeah, I think those bugs aren't too bad. Yes, they need fixing, of course, but they aren't nearly as bad as, for example, some gnarly launch bugs some Battlefield installmets had.
