I usually just play D&D by taking spells that will help the party take enemies down a little faster. Usually the DM will have an adventure set up for a party of 2-3 melees and a caster.. Which means most encounters are 1-2 enemies that are hard to kill and the entire party beats down on them, and a bunch of trash mobs (say low-level orcs, with ogre+troll bosses).
Here, a fireball is the best. It will wipe most the trash mobs out instantly, and heavily damage the bosses, allowing the melees to mop up with the rest in a round or two, and, what's most important, everyone has fun.
Not saying this is the best way to deal with the situation, it just gives everyone the opportunity to do something, rather than *glitterdust* *beat on blind enemies that can't fight back* *battle won*.
Also thanks to Aspenor on giving me another idea for when playing wizards.![]()
