Yes, but how many DMs memorized the ranges, durations and precise effects of each spell? I certainly didn't. I remember my players groaning every time they faced a caster (or a creature with spellcasting) because it would be a lot of time with me saying "Cause Serious Wounds!... okay... is that 2d8 or 3d8 damage... Now thie wizard goes... Melf's Acid Arrow!... wait, what's the range on that?... oh, okay... Shocking Grasp!... what's that 2d6+4? 1d8+3? hold on..."@wrecan : Her spell list isn't to bad. Its made up of rather common and popular cleric spells.

Fit every monster onto the size of a power card, so the DM can shuffle between them during combat.
Make no mistake: I'm very, very good at arithmetic, and generally fast as well, but I'm noticeably slowing down as I get older, and my players are far worse than me. Watching them trying to add up 5d6 is agony.
