Day 3 - Favorite Playable Class
Bards are generally my favorite class. I like Charisma-based characters, and I like "Jack of all trades, master of none" types. It's fun having a lot of options in front of you. You'll never outshine the other players, but you can bet the party will always have use of you.
My second choice would be archers, regardless of the base class. They could be a Ranger, Fighter, Arcane Archer, or even Bard, as long as they're build around archery.
