Spell slots, one of the best things Wizards has delivered for D&D!!
If you could unlearn 30+ years of D&D, I think you could readily digest spell points and mana if you were a reader of fantasy or a gamer who has played any game of resource management. I think spell slots would come across as bizarre and non-intuitive in comparison.
However, add all that tradition and sacred cow-edness and it's difficult for people to envision a Vance-free D&D. Slots are a pretty good compromise between Vance and Points. Far better than old school Vance or even the wackiness of 4e's daily/encounter/at-will approach. But points are just more intuitive and translatable to most fantasy settings.
I think the fact that low level spells now need to be cast as higher level to produce more/better effects actually supports a point system much better than in the old days when spending 1 point on a Magic Missile spell at 9th level meant you could do 5d4+5 damage unerringly (assuming the stripped-down, basic 1 point per spell level approach that was always as easy as it was imbalanced).
I'm eager to use points once I can actually get my campaign rolling.
Perhaps, but with those more flexible and easier-to-apply-across-a-wider-subsection-of-fantasy-magic-traditions spell points comes, I think, a greater level of analysis paralysis in attempts to maximize one's spell power for points. Do you blow all your points on higher level effects or span lower level pew, pew, pews? I can already see the spreadsheet macros now. If you thought the power attack bonus tinkering was bad in 3E, you ain't seen nothing yet. While situations and individual campaigns vary, it would put a much tighter restriction on spell design as even a slight difference in power or utility is magnified in the spell point paradigm. It leads toward the game being mathematically 'solved': there would be some master spreadsheet macro developed to give one the optimum amount of spell points to put into each spell/encounter given an opponent type, etc. Now this may be a fascinating and fun sub-game for some to play, I suspect it would lead to many becoming dissatisfied with the system in the end.
Or, I could be wrong. I have not used the current rendition of spell points, so I would be eager to hear the results of others who have tried.
You're right, except that it doesn't take a spreadsheet. The optimization is trivially done in your head on a spell-by-spell basis.
