I just finished playing a Land Druid (pulled the wrong card in a Deck of Many Things). Completely gave up on having a decent AC halfway through and ran around naked with AC 11. Miracle I survived that long, but it was fun and amusing. Compound this with rolling below average on every HD at level up. 26 HP and 11 AC at level 6.

Don't worry about it? I did for the first few sessions, but once I embraced doing my best not to get hit or caring if I did, I enjoyed things a lot more.

You're squishy. Embrace the squishy. Show your foes you don't care that you're squishy.
