The druid's Wild Shape ability looks overly powerful. At 2nd level, you can change into a brown bear, gain an extra 4d10+12 hit points, and this can be done twice per short rest?

Has anyone considered changing this to twice per long rest?

IME, it's not overpowered. Moon Druids have some ability to stand in the front-line, but I've found it to be much more limited than that of a fighter due to low AC. The extra HP are nice, but they tend to go FAST, and the damage can be a little meh. Admittedly, my players don't take a short rest after every fight, so the druid didn't start every encounter with 2 wild shapes ready to go.

I've found druid spells, such as Entangle, to have a much bigger impact on encounters than Wild Shape. While a Moon Druid certainly has spells, he isn't casting them if he's Wild Shaped (at least not until very high levels). On the other hand, we haven't played beyond 10th level, with most play at level 6 or below, so it's possible my opinion might change at higher levels.
