I'm looking to make a new character for an existing game, to start at 5th level. I am currently playing a wizard, and I love the versatility and non-combat usefulness of the character. However, a couple of players in the group want new characters, which is going to affect party balance. The new line-up will be a warlock, a lore bard (who uses a shortbow), a rogue, and me. I don't want to give up my wizard, but I think the rogue desperately needs a melee buddy, and the party needs more healing. A Life Cleric would fit the bill, but seems kinda boring, play-wise. Can I multi-class my wizard into a dex fighter (she has dex 15) or is that just silly? Are there other options that would help my party but are more than just a healbot?
