Dipping could work fine, if you have
a) no time
b) can't paint, even after many efforts
But in general, I must admit I look down on dipped armies. They just don't look as good and in general I think it shows a slight lack in interest. On the other hand, I rather play against a dipped army then an army that is not painted at all. A normally painted army (even drybrushed ones) looks nicer, it shows you have payed some attention to your miniatures and affection for your army, in your own style.
From this, you can of course read that I paint my armies 'the normal way.' Maybe my army is not 'Eavy Metal standard (although my Hochland army comes darn close) but it has my 'heart and soul' in it. Many hours of careful assembly and painting, with a result, I hope, my opponent will also please. I just love to look at an army painted by someone else, pick up a mini and watch it in close-up and talk about how he/she painted it or where (s)he can improve.
I've just started (once again) with putting a 4'x4' gamingboard on my diningtable and put my entire Empire army on it. And with that, I'm also assemblimg the last miniatures I have not yet assembled. Yesterday, I assembled a nice big unit of 25 Spearmen for my Nuln army (both 6th unipose and 7th edition minis) and an additional unit of Militia for my Hochland army. The last army is now almost completely painted (5000pts exactely) and my Nuln army which is the next project, is also comming along quite nice in terms of minis I have for it. Hopefully, I'll soon have some pictures for you all
