If you build yourself with alot of toughness, and self regen, you could “sit” at a mob & kill them after awhile. But dodging is there to help avoid the large attacks that many mobs have, avoid knockdowns/stuns, and get around the mob much faster then running. Some mobs put AoE’s on the ground with a red ring, & its perty much a signal to get out of that red ring fast with either running or dodging out. (Sometimes the ring appears around the mob, or where ever they cast it on you)
Building you character to be very tough though, you sacrifice alot of damage/support so you want to find a good balance between the 3 that fits your playstyle, while being efficient to a group setting (dungeons).
Kiting is much part of the combat, but the amount of it depends on what mob your fighting. Some only require just to move a tap of the key, while others require constant kiting (Risen Abominations build damage/speed with each hit).
