Does that work in AU/E?
It seems to me that a wizard with two readied spells and X slots will still just ready fireball and haste rather than phantom steed and fireball.
It works great in AE in practice, even better than you would expect on paper. Part of it is that AE pares the spell list down. Part of it is because the spells scale better. (So no point in taking a second attack spell as one of your 3rd level readied spells, when your 2nd and 1st level attack spells still work great.) Sure, those levels when you get your first slot of a given spell level, the caster tends to take the equivalent of
fireball or something equally flashy and direct. And I daresay a 5th level wizard with AE casting, and the complete list of 3.5 spells would be tempted to go with
haste and something flashy, over
phantom steed. But what you don't have is that same wizard at 7th or 9th level, now that he has 3 to 5 3rd level options, stocking up on nothing but the obvious. It's a cross between Vancian slots and the Sorcerer.
To me, it sounds more like each individual spell is going to be more flexible, the opposite direction of movement from 3.5, where spells with versatility were seperated into different spells with no versatility.
Note that AU introduced "diminished" and "heightened" spells--a version of each spell one level lower, and one level higher--that is automatically readied when you ready the base version. So if you readied,
sorcerous blast (AE fireball) as a 3rd level spell, you could also use a 2nd level slot to cast it single target or a 4th level slot to cast it with improved damage. I expect you are correct, and that 4E will build a similar but even more flexible way to modify spells. However, this is not necessarily instead of the AE casting, as the two changes are mutually reinforcing.
I dunno about Hero, but it reminds me of Power Arrays in Mutants and Masterminds
Well, that's no surprise, since the M&M versions are a direct analog of the Hero frameworks, the multiipower and elemental control.
