So I know this is something really small - but consider it the "straw that broke the camel's back."
Blood Knights are one of those figures I've always liked. I have always digged the Paladin theme in any RPG - but these guys? They had a fun twist to it.
They were a twisted version of Paladins. They weren't the type that would wait for the enemy to come to them, then risk their lives to defend the weak. No, they went over to the enemy and they got rid of them -before- they could be a threat to their people (at least, this is the impression I always got from them). They didn't have to worship the Light, they used the Naaru to force the Light into service - hence, "the true masters of the Light." They weren't "faithful" to the Light either, nor 'put your faith in the Light!' figures. They were faithful to -Silvermoon-. Their -people-. After the Sunwell was restored, they drew it from there.
They also had their Blood magic which was a nice twist. These guys may be arrogant and see themselves above the citizen and guards - but guess what? They used magic to make them powerful enough as the cost of their own health (Seal & Judgement of Blood - which later the Alliance tried to snatch with "Martyr" but didn't even last an expansion). They were truly dedicated to protect Quel'Thalas with their lives.
Of course, this was in the 'old' life of World of Warcraft. We've seen now that they have become rather generic paladins - especially with Liadrin that I swear spouts out "For the Light!" more than any Alliance Paladin (by the way, apart from boring Turalyon(poor guy), do you guys have any notable paladin at all?)
And now, today, the 'petty' thing that made me want to write this. In case you haven't spot it yet (as Alliance, you haven't), Liadrin appears from time to time from the Silvermoon portal in the portal room of Orgrimmar. She literally says "Blood Knights, form rank!" in order to take them on a patrol - and they're not even Blood Knights, they're just regular Silvermoon Guardians you see protect Silvermoon! Sure, they're named "Silvermoon Soldier" but they don't even have a blood knight tabard.
So, yeah. Paladins have just drifted away from being anything special past Wrath of the Lich King and now, Blood Knights just seem to be disappearing all together. Given how this is an MMO"RPG", I value atmosphere (guess that's my fault in this case) and these things are just piling up. ;_:
Do you guys have some of these moments with something else in WoW that you felt was amazing but over time, Blizzard just made it all washed out to take away all the flavor it had?
