"Is there a limit on the number of times a character can be risen from the dead by the Lich King? I ask because of the Blood Prince Council encounter in Icecrown Citadel. Prince Keleseth was already undead when you fought him in Utgarde Keep. So that means he'd already been risen from the dead before.
Seems to me the limit is....until Blizzard has milked the character for all it's worth."
Well, all of the Blood Princes were high/blood elves in their previous lives. There are no "living" San'layn.
Not to mention -- I had this argument with my guild the other night -- we're in the stronghold of a guy whose claim to fame is raising people from the dead. I don't think it breaks from theme to have someone that you've slain before brought back again.
"Why don't we just go back to Stratholme in the CoT and just kill Arthas? I know it'd make some parallel universe or something, but it doesn't make sense in the first place to go back in time to help something happen the way it's meant to happen, which'd mean we would've had to been there in the first place, but how can an event that took place in the past only happen by thing that happened in the future, which creates a paradox?"
The Caverns of Time instances are time "pockets" -- the Bronze Dragonflight has contained those moments in time to prevent them from altering the real timeline, but the effect is only temporary. If the Infinite Dragonflight did manage to fulfill their mission -- killing Arthas, for example -- then the timeline would be forever altered.
As to why we don't kill Arthas, the general idea is that while his actions in Stratholme were repugnant, if he hadn't purged the city, then the plague would've spread through the Eastern Kingdoms much, much faster than it did. It's for much the reason that we protect Medivh in the Black Morass -- if he had never summoned the orcs through the Dark Portal, then the New Horde would never have been formed and the Burning Legion would never have been defeated on Azeroth.
