Well...these rants come up fairly regularly. The simple answer, as Dafan so correctly provided, is that if you don't like an item then sell it. Do you use the Holy Avenger, Carsomyr? That item can be unbalancing if used incorrectly. Do you use the Ring of Gaxx? That also can be unbalancing. I could go on and on about almost any item...
Now...since we're all sharing opinions, here's mine: If I could make one suggestion to Bioware, I would suggest that the Cloak of Mirroring have a finite number of charges...after which it is unusable. Like, maybe 20-30 charges...
Just my 2 cents...
