If you do it on (N) pretty much any job can go into these with no prob. (D) Most ppl gonna go with the easy set up like you said. But if you want to get a group of diffrent kinds of jobs then by all means set one up. I've done alot of the (D) fights on my dnc but most of the time I have to set it up myself or go with my friends because they trust my dnc. Now i have rng that does get me into alot of things but mainly use it for shout groups if i dont feel like buidling my own pts.
