World of Warcraft Producer Tom Chilton: Exactly, exactly.
Worldofwar.net has a video interview with the Producer of WoW, Tom Chilton, in which they ask some very interesting questions.
The second and last part of this intnerview has been released as well.
Basically the interviewer pinned the man down on Paladins vs Shaman.
"As soon we start having our buffs or benefits extend to the entire raid then how does it really matter how you make the entire group composition."
If you listen to that entire q&a in which he details how you'd have only one Strength of Earth Shaman (one paladin does Greater Blessing of Strength for everyone who needs it) or one Stoneskin Shaman (one paladin does Greater Blessing of Sanctuary on the entire raid) he details that if a Shaman's Mana Spring would hit the entire raid (like Greater Blessing of Wisdom) it would be really bad...
Flaming hypocrite

Or will we see Paladins nerfed in that their Judgements and Seals can only effect their own groups?
Will they then be able to grant up to three Seals per player in their group?
Interesting.

They have a truckload of info available.
PvP system, sets, specialization, pigeonholing.
