Surprising? Not in the least if you've been following the official beta information and, if you're a naughty boy like me, the beta leaks floods. What's of real interest to me is how this is going to;
a) Affect end-game RvR (theoretically, as it hasn't started yet) now that the major targets have decreased from 6 to 2. Is anybody going to bother to fight in the Elf/Dark Elf zones now that there is no capital city to push towards at the end of the road, or is Mythic going to allow all RvR areas to affect the territory control that leads to Altdorf/Inevitable City?
b) Affect group dynamics in the low level zones, at least before you get to the level where different factions on each side of Order and Destruction easily mix together, now that 2 factions have lost their tank and 2 have lost their melee DPS. If the rewards for quests are not too faction-specific, I'd wager we'll see a number of melee DPSers from, for example, the Dark Elf and Chaos factions head on over to Greenskin land early on in order to ensure they get a group when they want it.
Either way it looks like Mythic has got half of the content for their first expansion sorted then.
