Newb Question on Auto-Attack

[Darguth]

Coming back after a very long absence. Played a Ranger (dear God, why?!) and eventually a Cleric up through I think LDoN was my last expansion on live.

Anywho, contemplating restarting and I can't recall if your character will still auto-attack while casting (mostly for hybrids like Bard/Pally/SK/Ranger)?

Thinking about rolling a bard and wondering if I'll ever really do any melee or if it's pretty much just non-stop song twisting.
