A fresh horde character showed the problem starkly. All through the classical levels, Vol'Jin is now sitting in Orgrimmar as warchief. Okay, Garrosh turns up in Outland and Northrend, but the fresh character is unaware of 'later' events. However, when she reaches the Twilight Highlands, Garrosh is spearheading the assault, as Warchief. He's in the Stonetalon Mountains as Warchief. Later he's in Pandaria as Warchief. And Vol'jin is plotting against him. What?
That could be partially fixed by putting the portals to Outland, Northrend, and Pandaria in the Caverns of Time, removing all other routes into them, and replacing Garrosh in Kalimdor with another NPC. But it's hard to keep all these mixed stories straight. Anyway, I was in Dalaran recently, and I was amazed to see that Jaina has let the horde back in. Did Theramore suddenly get undestroyed? Did the duplicitous Sunreavers do something trustworthy? What's going on?
After we invaded Orgrimmar, defeated the Kor'kron and brought Garrosh to justice, you would expect the Alliance to install an administrative leader in Orgrimmar (perhaps Jaina would have been the right person for the job), and to restore the destroyed or desecrated lands of the Stonetalon Mountains, Ashenvale and Azshara to Night Elf care, Instead, orcs and goblins continue to run riot through these areas. And rather than getting rid of the aggressive alien invaders right here on our doorstep, we're off in Draenor, invading another planet.
It would be fantastic if the night elves could have their lands restored, and the orcs and Draenei could have their planet restored and we could all live in peace on our own planets. Then all we have to do is get rid of the scourge in Lordaeron.
