Fact is, Larian has implemented the Druid's wildshaped forms in a way that makes them weaker than 5e rules. It's ridiculous that you blame your problems on BG3 being dnd when if they were actually closer to dnd you'd have less of a problem with them.
Comparison:
Polar Bear 5e abilities:
Hit Points 42 (5d10+15)
[...]
Multiattack. The bear makes two attacks: one with its bite and one with its claws.
Bite. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: (1d8 + 5) piercing damage.
Claws. Melee Weapon Attack: +7 to hit, reach 5 ft., one target. Hit: (2d6 + 5) slashing damage.
Almost 50% more HP than Larians polar bear and two attacks.
Dire Wolf 5e abilities:
Hit Points 37 (5d10+10)
[...]
Pack Tactics. The wolf has advantage on an attack roll against a creature if at least one of the wolf's allies is within 5 ft. of the creature and the ally isn't incapacitated.
Actions
Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one target. Hit: (2d6 + 3) piercing damage. If the target is a creature, it must succeed on a DC 13 Strength saving throw or be knocked prone
100% higher HP than Larian. Automatic melee advantage (though, yeah, sure, Backstab already means they have that anyway) with allies and an automatic if weak chance to put enemies on the ground.
Instead of this they get a 1d4 attack that makes a later attack be a critical hit. Not weak, but at the cost of another a 2d6 attack?
Hit Points 26 (4d10+4)
Bite. Melee Weapon Attack: +5 to hit, reach 5 ft., one creature. Hit: (1d8 + 3) piercing damage plus (2d8)poison damage. The target must make a DC 11 Constitution saving throw, taking the poison damage on a failed save, or half as much damage on a successful one. If the poison damage reduces the target to 0 hit points, the target is stable but poisoned for 1 hour, even after regaining hit points, and is paralyzed while poisoned in this way.
Only 6 HP difference, but still more than Larian's. 3d8 damage instead of 1d8, and two of them in a non-physical damage type.
In exchange for that Larian's spider gets the ability to use Web every turn and as an area attack which can also be set on fire, and the ability to make the enemy Poisoned (disadvantage on attacks) on a failed check and no effect on a success but it's DC 13 instead of 11.
