Playing a wizard here too, but at level 3 so far, and having a blast discovering the game. It feels exactly as I expected. Regarding your feedback, I agree on the sound of your running, would limit it to footing only and remove whatever clanking.
Don´t know about spells yet, not enough of them to elaborate a solid feedback. I suppose it would be cool to have a range of DD spells, with different raw damage, casting times, elements and ratio damage / mana. This way you can actually make decisions as a wizard to handle encounters, both in solo and group play. Something that allow you to kill blue monsters with efficient spells to reduce downtime, to cast big, unefficient nukes to quickly dispatch a yellow mob that aggroed you from behind, and such. Regarding utilities of course, they will be welcome, but I wouldn´t like to see all classes here being to do everything. The more unique buffs, debuffs, DDs, CCs, the better for the health of the game imho.
Keep enjoying you wizzie, hope to catch up and see you around.
