If Blizzard had wanted to make agame apart, or integrate them into Titan, I would have had no problem with the existence of pandaren and their lore.
But their endless stream of peaceful, happy drinking Starfleet explorers atmosphere is totally out of Warcraft context.
I come back every expansion to hate something and to WAR, not to solve problems about evil spirits and find reasons about what is worth fighting for.
I figh for the hate I feel for my ravaged lands and my murdered heroes, I fight for the lust of revenge and the desire to shed the blood of my enemies until the rivers run red with it, I fight in the name of the Light and with the forces of the elements to resolve unquenchable blood feuds with this alliance that is the Horde.
I fight for Jaina Proudmoore and Theramore, I fight for Vrynn and his past suffering, I fight for Lothar, for Alleria, for Dannath, for Uther.
Pandaren, you're a wonderful and fresh race, but this conflict is beyond you, and you simply do not share the fury of our races nor will you ever understand it.
You will never understand the joy I feel when I slash a blood elf in two or cleave an orc's head off his shoulders. That is the real war.
Go back to your Mists and take care of your evil spirits problems, the rest of the world is at war with its own past, and will be forevermore.
Garrosh has seen to that.
