As a 99%-of-the-time single player, I like this idea
I rarely do any Undaunted stuff because I'm not so much the grouping-type of player, and I finished the Fighter's Guild questline a looong time ago with all characters. So yeah, this kind of Mercenary jobs would be awesome!
I generally play solo myself, so I enjoy single player options.
The daily dwelve quests in orsinium were nifty (though I kinda would have wished for more varietee... like, say, two differnet quests per dwelve, so you never know if you'll get sent to that one place to collect harpy eggs, or steal valuables from the winterborn for example)
Of course, there are thievy quests as well nowadays... we shall see what more may be to come. I expect daily assassin quests with DB, and hopefully every new DLC region will include soloable dailies...
