With all the changes we have been getting with D2R, I believe there are some changes that would benefit the Druid’s usability and remove some of the friction from the class.
Spirits. They have no health to speak of, even if you level them all the way to 20. Most often, this defenseless little guy will float directly into combat and die instantly, negating any effect they give. At the minimum they should be given damage reduction and health, maybe on par with a tankier minion. If the concern is them becoming a damage sponge, making them untargetable could be an option.
Spirit of Barbs could do with a fresh coat of paint like thorns got, or maybe a different flavor of ability? Mods like PD2 open the door to that Spirit giving deadly strike, but giving it something to do besides being a prerequisite to Heart of the Wolverine would be nice.
Hunger is still bugged and misses half the time. I don’t know if this is an engine specific thing, but this is a skill on the shapeshifting tree that simply does not work properly and should be fixed. Why are we okay with a skill just straight up being broken?
