But why would you want to make a dexterity based warrior when it doesn't make any sense and is a complete waste of resources? And I don't think you'll have a problem with building something like a rogue with high health, should be possible.
I have a dual-wielding warrior and rogue Warden, and they both have different feels in the way they play. The moves on the dual weapon tree may be the same, but the character has different moves and other specialized talents based on class. The specialization is really key there, because warriors, I found, are better at crowd control. If I unlock the Templar specialization, I can dispel enemy magic and knock enemies back with Holy Smite. I didn't really lose anything putting lots of points in dexterity in my warrior.
In the end, the str-based rogue ended up being my favorite, but the hi-dex dual wielding warrior felt pretty special to me.
