Dumb Damage Question

[Arnabas]

I have never really been one to chase numbers and have instead played according to what feels fun, but I am trying to decide between a Blaster and Corrupter for a character concept I have.

I don't usually do this, but today I was looking (in character creation) at damage values. I was using Electrical Blast. Now, I have always believed that Blasters do more damage, but looking at Electrical Blast, it gave higher "Average Damage" on each power to the Corrupter but lower damage in the details that followed.

Example:

Blaster Charged Bolts. Avg Damage: 12.30/ 8.20 energy damage on target

Corrupter Charged Bolts. Avg Damage: 20.90/ 1.90 energy damage on target.

So, does the higher Average Damage (if the values are even correct) reflect Scourge? Or is it something else, perhaps an error?

Yes, that includes scourge, Mids does as well, which makes things equally confusing.
