No, this is not true. The 10 man and 25 man versions of dungeons have completely different loot tables, the item levels are not even the same. I can't common on the number of drops per boss because i didn't make it that far in beta but the gear itself is different, the 25 man gear is better than the 10 man gear because the 25 man version is more difficult.

No, thats not true. There are completely different loot tables for 10 and 25 man. The 25 man of Naxx drops better gear than the 10 man version. There have been rough alignments saying that the 25 man version of loot from one instance is about on par with the 10 man version of the loot from the next instance. If it was implemented this way in TBC that would be like a 25 man version of Karazhan dropping gear on par with the 10 man verison of SSC.

However the tiered loot from the 10 and 25 man instance have the same model with different coloring, and the 25 man instance have vastly superior stats.

Why are all these old questions about Championing and 10/25-mans coming back around? They were all answered months ago, and now they come back to waste away the last days of "Ask a beta tester".

Different Loot Tables
Different Raid IDs
Different Raid Timers/Cooldowns
Default Northrend faction without a tabard on
Championing only works in level 80 dungeons and raids.

Thank you very much! This makes me glad, because, if we were just going to get the EXACT same loot, then it's like "What's the point?". I was curious because I stay well up to date with Wrath news, but during a recent guild meeting discussing wrath and our plans when it launches, our guild leader said this, and that got me a little worried. But now I can tell him he's wrong! Thanks again, guys. :)
