Suggestions needed for building a high damage rogue

[Technique]

I do more damage with heartseekers. Tested on timed runs.

Upon seeing your post, I went to test, once again, Agile Heartseekers of Brutality against Agile Lifethief of Potency.

The Heartseekers hit far faster-- but the Lifethief can do up to 2.5 times the damage of a Heartseeker hit.

It took about 30-40 secs to kill Jarl with the ALP, and about 45-55 with the Heartseekers (about three solo runs each).

I actually want to know what tests you did. Maybe I'm missing something.

Maybe ill buy some of these^ and test it out also, I'm currently using the heartseekers. The lifetheif have decenct damage and the 15% heal seems useful
