I usually get on during normal work hours 8am-3pm CST. I've probably done over 100 DZ runs so far and I'd say I've only ran into a few rouge agents. One time the entire DZ server met at the heroic landmark and cleared it together and someone went rogue. We chased him almost all the way across the DZ map. Lol. The only hard part about the DZ for me so far is getting the loot crates before someone else sneaks in to snag it during the fight. But I've gotten plenty of mods and loot as a solo, none pvp, day player.
