What isn't clear from the chart though is what I believe to be the crux of Vitality's question. In CoX, every AT (class) had [url=http://tomax.cohtitan.com/data/powers/tables.php]innate mathematical modifiers[/url] that determined how strong various qualities of powers were for each class.

For instance, a power like [url=http://paragonwiki.com/wiki/Radiation_Emission#Radiation_Infection]Radiation Infection[/url] would have stronger debuffs when used by a Defender than that same power would have when used by a Corruptor. Likewise, a Corruptor would deal more damage with their attacks than a Defender would deal with those same powers. Despite having the same powers, the Defender provided stronger support while the Corruptor provided more damage.

I believe Vitality's example was meant to highlight this kind of difference between Tankers and Brutes. Given the same powers, a Tanker would have better armor and HP while a Brute would deal more damage. In other words, a player's choice of class affected the various qualities of their powers, even if two classes had the exact same powers. It was this statistical inequality that gave classes strengths and weaknesses in terms of performance.

Assuming my understanding is accurate, let me try to rephrase the original question: will powers perform differently when used by different classes in CoT?

I believe that the answer to that is "basically yes" because your class will determine what your HP and your Primary, Secondary, and Tertiary Power Set choices are, and the numbers for a set will be different depending on if it's used as a Primary, Secondary, and Tertiary Powerset.
For example, "Burning" will do more damage as a Primary than as a Secondary choice. And more as a Secondary choice than as a Tertiary choice. Much like Ancillary Pool Powers in CoH.
I think. Please someone correct me if I'm wrong.

Almost, but I think it's important to distinguish between numbers that [i]vary by primary/seconary/tertiary[/i] and numbers that [i]vary by class[/i]. For instance, in CoX, a Corruptor would deal more damage with [url=http://paragonwiki.com/wiki/Dark_Blast]Dark Blast[/url] as a primary while a Defender would inflict more powerful debuffs with it as a secondary. This is just one example to show that CoX powers varied by the class using the power and not whether that power belonged to a primary, secondary, or pool powerset.

In my opinion, this is how it should be. Each class's statistical strengths and weaknesses should be reflected in all of their powers regardless of where their powers are selected from. This should hold true for every type of damage, buff, and debuff a power can deliver.

Of course, that's assuming such class modifiers will exist in CoT which I think is the question being asked here.

Empyrean has the basics of it right. The distinction between Primary and Secondary set type by Classification i. The chart was ment to imply this difference but it wasnt explicit so I can understand the confusion.
