I had a silly idea for a group of gnomes to team up with a Goliath who shifts into a bear to serve as a battle platform for them to ride and attack with lances/shoot bows/cast from. Maybe mount a ballista or heavy crossbow on his back. You know, silly ideas.
But before I present this idea to my group/DM, I'm curious exactly how far this bends the rules: If a Goliath Druid wildshapes into a brown bear, does his racial Powerful Build trait carry over when he's shifted, so he'd count as a Huge creature for carry weight?
