I don´t agree. It´s true that "Darkness descends" is a classic and better than the rest of Dark Angel discography. However, the other albums are quite good too.
"We have arrived" is quite primitive but with a couple of excellent songs plus the first "Mercyless death" version.
"Leave scars" and, above all, "Time does not heal" have a little too long songs but some of them are brilliant like "Trauma and catharsis", "Act of contrition" or "Time does not heal".
