I get where you're coming from here, but the basic crunch of it is delivered on a 3rd Edition base. If you look at a 4th Edition Wizard, they have at-will, encounter and daily powers, just like any other 4e class. If you look at a 5th Edition wizard, they have... spells, broken down by spell level, in a way that feels very familiar to 3rd Edition players. Some of the spells feel like they haven't changed at all from 3rd Edition.

Here's 3.5th Edition magic missile: https://www.d20srd.org/srd/spells/magicMissile.htm

Here's the same spell in 5th Edition: http://5e.d20srd.org/srd/spells/magicMissile.htm

Very similar. The 5th Edition version is a bit simpler to read/understand, but frankly if you sit there at the table and think you're casting the 3rd Edition magic missile you will get it right 8 times out of 10.

And then on page 20 of this quickstart rules, you can see the 4e magic missile, which is a very different spell altogether: https://issuu.com/biggerstaffhosting/docs/quickstartrules
