I know most people recommend a wizard because it lets you experiment with the spells.
However... I don't learn well this way.
You know the saying "Practice makes perfect"? It's a bit inaccurate. "Perfect practice makes perfect"
If you practice wrong, then all you'll learn is how to do better at doing things wrong.
And that's what I fear. I fear that I'll make myself learn how to use spells wrong. There's a lot of spells to learn, both from scrolls and level ups, and there's precious little platinum to buy all the inscription materials with early on.
Assume that I'll be partying when I can, and soloing when I can't. Also, Warforged, because why not.
This is what I know so far:
Tier 1: Master's Touch, Shield, Hypnotism, Repair Light Damage, ????
Tier 2: Repair Moderate Damage, Blur, ????
Tier 3: ????
Tier 4: Wall of Fire or Acid Rain?
And that's about as much as I know.
