Is it needed/recommended to complete Campaign quests?

I did some questions in Dragonflight, but was having so much fun PVPing I never really got past the campaign quests in the Walking Shores and I already dinged 70.

Is there any reason I need to, or should, go back and do the Campaign quests or any other Dragonflight quest line (other than the Dragon riding ones obviously)? I’d prefer not to go do them, but don’t want to miss out on anything end game if I do.

Thanks!
