I think I see where my problem is. For the most part, I've always believed magical people seek magical solutions while technical people seek technical solutions.
There's nothing wrong with a magical person resorting to a technical solution or vice versa, but it is important to differentiate the two and the motivations behind them. There needs to be a build-up of circumstances leading to that decision. Here's why.
In the magical world, a computer is nothing but an abacus and a laser is nothing but a torch. In the technical world, a wand is nothing but a stick and a staff is nothing but a cane. These are two diametrically opposed conditions each of which takes a lifetime to adapt. A being from a magical realm where faith and will is the general rule (the ideal world) isn't going to go search for a rocket launcher first thing when the nearest elm tree will give him a more potent and effective weapon.
However, I'm not an anime fan. What little I have seen of it, in anime both worlds appear to be fused to the point of where it's difficult to determine one from the other. Yugi's puzzle is tech, while the spirit within is magical. Pokemon balls are tech, but the creatures they keep - even though they are genetically manufactured - are magical.
Even in the D&D world where Dorian comes from, a human/drow hybrid might be that much more inclined to resort to tech rather than nature magic like his elven cousins. Since the A&C stories are present day, I can even see Dorian picking up a modern device if he had access to one because shapeshifting is his only magical ability and might not help him out.
Tora would probably be the best one to elaborate. Tora, what do you think?
