Yes, it is entirely worth picking up. do remember that the shield stacks with your resistances, so if you're getting a 450 shield with 50% damage reduction to physical damage, the effective health of that is 900, same if you calculated that to magic damage. the shield should be picked up if you're dueling/brawling so long as it doesnt put you in a bad position to either continue fighting or keep your friendlies peeled for. Poppy is most effective when being built resitances, then health, then damage. at most you should have 1 fully offence item <namely BC> and one hybrid item <such as Iceborn or Maw Mal> and the rest of your items should be tank.
But...it takes like a second or two to walk away, grab the shield, and then walk back in. Can you justify basically stunning yourself for a 450 hp shield in 5v5? Keep in mind this a shield not a heal.
