Goblin Rogue: Sadly, a big draw of Goblin, their Cunning Action light, is basically worthless as a rogue. This makes me sad that it's such a bad combination. I play AL so it's especially not worth using my +1 book for it, even though I like playing small and cute characters.

Kobold barbarian: What as a strength penalty and already gets easy advantage without using reckless attack?! This class. For real, -2 Str hurts and I wish kobolds were buffed by having the penalty removed.
