In patch 1.03, a cap was added such that any attack done to elite enemies (e.g. lieutenants, mages, saarebas, and rage demons) is capped to 40% of their health.
So now however I spec my dual-wielding rogue, I never kill them in a single hit: my max tops out at 80% (40% per hand). The lacerate talent gets around this, but it only procs 10% of the time.
Since the rogue thrives on single target assassination and taking priority targets out of the fight immediately, I was hoping there was a way to remove this cap.

This mod (which has no decent name) claims to remove the cap, but the mediafire link is broken and there are no files listed on the Bioware project page anymore, but according to related comments it used to work.
Unfortunately that just tells us that you could make your own mod to remove the cap.
I do not know of any other way to get around the cap.
