Most people tend to go bow/dual-wield early and remove the dual-wield points later, removing those weapons in favor of a stave, and use it to cast spells.
Here is a topic that discusses what you have asked in some depth:viewtopic.php?f=39&t=38436&p=159742&hilit=temporal+warden+dual+wielding#p159742
As you can see the big consensus is that archery is superior to dual-wielding in TWs. That doesn't mean that the latter is not viable, though. Imo I just think that all the mobility and utility from the spells you get synergise better with archery. And as mentioned in the topic, you end up being a really boring archer playing a very interesting and diverse class.
