I find it rather difficult to resolve how quickly the Zandalari went from a benevolent group of cross-factional trolls to a threat to all of Azeroth mid-expansion in Cat. When Cat first went live, I went to the small islands in Stranglethorn to see if there were any remnants of the group I spent literally weeks grinding rep with. I wasn't given much in the way of lore as to why they suddenly turned malicious, but now theyre a recurring villain that will again pop up in MoP? Its kind of like that quest where you run beer kegs to Brewfest only to find out the guys drinking the beer wear brown shirts and want more 'lebensraum.'
