Nobody in my group wanted to do any sidequests when I was playing as a faery dragon that specialized in support spells and we got wind of an undead outbreak. Faery Dragons are extremely against undead, so my character went to stop the zombies all by himself and lost an arm, an eye and nearly died because my party members were metagaming dumbasses trying to go straight for the BBEG at level fucking 2.

Even the DM was disappointed and then gave me some sick new powers to allow me to be better solo if it happened again.
