for 10-man as long as 7 people in the raid can pull at least 2200 dps you don't need to stack polarity - all DPSers can spread out across the entire back of the room (some on the edge of the platforms for example) and you will kill him just fine before enrage.

For 25 man each person needs to pull 5500 dps so you do need to stack polarity, since 5500 dps is tough unless you are geared in ulduar25.
Dpsing him down without the stacking buff in 10 man is definately accomplishable...

Thaddius has 30000 health and a 6 minute enrage timer in 25 man, so it really doesn't require 5500 dps per player... if you could assume that no playes would be wthin 10 meters of one another and none would die, you'd need around 4250dps per dps and 1400 dps on your 2 tanks (assuming 4 healers)

As a player, this is one of my favorite fights to fight.. but as a Raid Leader, one of my least favorites to lead.
