Druid is underpowered compared to every other class. I brought this up a while ago.
1) Heat metal is broken, targets weapon only and not armor and doesn't give a choice.
2) Few if any good ranged options
3) most spells require concentration, without the other feats this is not helpful as the enemy AI prioritizes caster who have concentration.
4) animal forms are underpowered for combat, specifically the combat animal forms. Bear is particularly bad.
They could "solve" bear by giving it rage, otherwise it has no business tanking. It has no AC, it just has a lot of health which isn't very useful on its own for tanking. Its attack is also underpowered.
Its sad that the Rangers summoned 'pet' Boar is better than any druid form.
