Nothing to report
I was able to download and install it with no trouble.
However, my old computer system is really dragging right now. Even on the live version I run at about 6 fps. The new expansion has greater system requirements so my expectations were low.
I flew through Stormwind, running at about 4 fps. Got to the first quest, which sends you into a 5-man scenario.
At this point I remembered that I had no add-ons, so none of my ability bars were configured. Oops.
None of that mattered. I made it through about 80% of the scenario, and then it crashed. Reloaded, went in again, and got to 50% before it crashed. Then the server crashed.
So, no joy in this first run through. I’ll wait a few days and try again. In the meantime, I’m researching new computers that are in my budget.
