Bah, you crazy kids and your fancy-schmancy newfangled 3rd and 3.5th Edition rules!
Why, when I was your age, we didn't have sorcerers or see invisible spells. We had to put up with rulebooks claiming to have been authored by Gary Gygax, with 100 gradiations of Strength between Strength 18 and Strength 19, and negative armor classes, and to-hit charts (charts!) for each different kind of character class. And weeeeeeeeee liked it!*
*) We especially liked the part where fireball and lightning bolt spells had no upper limit on the number of damage dice they did -- a 35th-level magic-user would cast 35d6 fireballs. Ah, those were the days!
