Yeah, even my Land Druid finds it incredibly useful.
Oh, we need to track someone?
*Becomes a Wolf*
*Rolls Survival tracking check with Advantage*
*Finds them easily*
Oh, we need to climb to the top of a tall rugged chute?
*Grabs grappling hook and rope*
*Casts Guidance*
*Becomes Panther with 40' climbing*
*Uses Guidance*
*Climbs easily*
*Fastens and lets down rope*
I think it lets a Druid become an incredible 'skill monkey' due to the individual abilities the animals give you. Fast movement, burrow, climb, swim, fly, darkvision, blindsense, advantage on perception rolls, etcetera. That sort of thing can trivialize a large number of obstacles.
And we have a Warlock so we short rest frequently. I rarely run out.
It's frustrating for the party's other skill monkeys.
