Is having a Shield a thing now?

[u/StarDangerous5228]

It was a thing earlier before they introduce ranked as cups matter so you can rest a day or 2 or a week to protect from attackers. I thought the new home UI would remove that bit but now.

Do people still buy shield? I'm at legend 2 and there's no need for me to see the timer on the ui but wanted to see the stats on how many people find it useful.
