As a start I want to give you my opinion of the evergoing subject “Horde is evil! No Alliance is evil!”
We can clearly see the trend of old Horde heroes from the past games that’ve become big bad bosses in WoW. I’m talking about Zul’Jin and Cho’gall from Tides of Darkness, not to mention that Deathwing, the additional hero in the WC2 expansion set Beyond the Dark Portal, will most likely be the finale in Cataclysm. Horde and Alliance are both factions containing different races and nations. The thing with horde is that their allies and pacts during the years, such as Mannaroth for example, have been questionable. “Allies come and allies go. That’s politics." – quote from Valeera Sanguinar in the official WoW comics.
So... at least three well-known Hordies have gone bananas. (Not literally bananas, I know the lore works, but you get my point) Where are all the allys? Some people’d probably mention Arthas right now, but... no. Simply just no. We could all notice while we played that he had some attitude problems in the very start of WC3 where he was first announced, and that he’d become an antagonist in the future. Arthas was made by Blizzard to become this great villain, just like Darth Vader.
Can Fandral Staghelm be sorted in this category? I guess so – but can you really compare the status and awesomeness between a non-playable guy sitting in a tree for six years in WoW and a guy like Zul’jin? That’s up to you to decide. To meet up with these big names in my book, an old hero like Turalion would have to do something drastic. Also the status on Sylvanas sister, Alleria from WC2, says: “missing in action”. Can we expect to see her again? As a boss that’ve finally returned in Cataclysm? The answer is no, because people don’t wanna see nice ordinary humans, elves, dwarves and gnomes as big fat final bosses. We want see evil trolls, scary big ogres and dangerous dragons. Why do you think Blizzard chose Saurfang to be a boss in ICC and not Bolvar Fordragon? The fact is, despite what people say – Horde has less morale than Alliance. That’s the whole point with Horde. They are our very contrast, that’s what makes them cool. That’s at least the reason why I like them.
So to sum this up... I’m totally looking forward to watch Garrosh go bananas in the next expansion.
