Need help on basics of Hammond!

Just got interested into playing Hammond after I got some good value with him in Mystery Heroes so I decided to play him a bit in qp but as you can tell it doesn‘t work as well as in mystery heroes.

So my questions are the following…

• Any Video/Youtbe recommendations ln where I can get useful information on how to play him

• any tips on grapple Hook usage?

• How do I play around my team? When do I engage? On who do I engage

• any other tips for getting better at him?
