Correct. As stated above through the thread, it's only a total of 10% increased damage, plus the 5 energy per combo point.
The 7.2.5 wording could be confusing to some I guess, but as per the build from the other day (Build 24163), it has been corrected to clarify that it is not 10% per combo point, which would be outright goofy.
Ah, thank you for clearing up the confusion!
I was genuinely not understanding why everybody was on a different page, and as it turns out, the only one on a different page was myself.
Apologies are in order. Now i can clearly understand why other people find this talent underwhelming, as I now find it to be nowhere near as good as I thought it was!
