My PW is level 101 (26/30/45 I know its a little out of whack, I'm a teacher and run jobs while grading papers, and I grade a lot of papers )I currently have level 5 shield sap and a Barrier of Ooze (18311 cap).
I was in VG earlier getting looking for my Barrier and after I got it decided to see how high of a mob I could take out, so I found a level 38 Ostarae. I was able to kill the mob only using Shield Sap. I never fired a single shot. The first 3 saps pulled ~7-8K and the last 14k. I know that I am not balanced, but a balanced character at level 101 would have a CL around 33-37 and would still be able to do this, even though they are 1-5 CLs below the mob.
I just think it is ridiculous that I can kill a mob 12 CL above mine using only shield sap. If this is how it is suppose to be, I won't complain, but it just seems a little out of balance to me.
