Lol, a CoT Strathalome? Coincidence, I was telling my guild today how the new expansion should have a new CoT instance like strat or scholo, maybe a CoT 25-man that takes place 10 years in the WoW future. That would be complete and utter, awesome.
As from what I HEAR the lich king is supposidly a 25-man, and he also drops his Legendary 2-handed sword, Frostmourne. Much of that is debatable for I hear it only through rumors.
As the Death Knights go, I always thought of them like Dark paladins. Paladins are Warriors with preist spells, so I assumed Death knights were the oposite, Warriors with Warlock spells. Drain life, summon minions, etc. Also can't wait to try out that new "Rune" system for them. Seems similiar to the "Medallion" style of play in Devil May Cry 2 (God rest that piece of crap)
And no, outlands will never be deserted, who would want to leave that place? Its a gold mine. As would the 10-mans. Who WOULD want to leave karazhan?
