I hear ya, but depends who you raid with . My group has always had dedicated relic holders and I always was on oracle duty . I have done it before and had not many problems with it . Mars is easy as you only have 3 goblins to take out . Venus is where it can usually go wrong but in our group we generally run corrective measure as heavy so the non relic holders kill the praetorian before the relic holder even gets down there . And then we can smash through the oracles .
