Third omni is hard. I do believe that it should be avoided by beginning writers because when it's done badly, it's painful.
To really make third omni work, you have to have your own, individual narrative voice (and a new one for each book or project!), plus you need to have individual and distinguishable character internal monologues and voices. If you're doing third omni right, the audience should be able to tell whose eyes they're looking through even before you tell them. This is really, really, freaking hard. It takes years of character development and moving words around, plus an insane amount of subtlety and sleight-of-hand. You're not going to pull this off in a first-try, pulp genre fantasy that you crank out in three months. You're just not. So much of the market right now seems to be written so fast (Gotta get those sequels out! Gotta get ten books out before you can make any money!) that I think that first or close-third, with their limited perspectives, are the only ways that people can keep their word counts up.
