@ChrisPerkinsDnD since two-weapon fighting specifies Attack action, not Multiattack. I suppose that will modify CR

@daedel @ChrisPerkinsDnD @JeremyECrawfordany answers on this topic? I'd say no – I believe that multiattack is its own action, rather than a subset of Attack

@mikemearls That's correct. Multiattack and Attack are different actions. @daedel @ChrisPerkinsDnD

Since a Barbarian/Druid with two attacks in bear form will still only get its normal multiattack of bite/claw. But in his wolf form he will now get bite/bite. This makes absolutely zero sense and makes the bear form inherently worse from this point on.
