There's like 20 tweets on that link. This one looks like the most relevant:
But that doesn't seem to justify your position.
And this one seems to support
@Oofta's argument that the DM can rule otherwise:
For the most part, tweets about hiding are only about whether or not you can attempt to hide in the first place, and do not establish how effective it is to take the hide action when observed while entering cover or when repeatedly hiding in the exact same spot.
However, Jeremy Crawford's Twitter account is no longer an official rules channel. The
Sage Advice Compendium, which
is the official channel, says that very clearly on the first page.
The Sage Advice Compendium does say this:
Do the lightfoot halfling and wood elf hiding racial traits allow them to hide while observed?
The lightfoot halfling and wood elf traits—Naturally Stealthy and Mask of the Wild—do allow members of those subraces to try to hide in their special circumstances even when observers are nearby. Normally, you can’t hide from someone if you’re in full view. A lightfoot halfling, though, can try to vanish behind a creature that is at least one size larger, and a wood elf can try to hide simply by being in heavy rain, mist, falling snow, foliage, or similar natural phenomena. It’s as if nature itself cloaks a wood elf from prying eyes—even eyes staring right at the elf! Both subraces are capable of hiding in situations when most other creatures can’t, but neither subrace’s hiding attempt is assured of success; a Dexterity (Stealth) check is required as normal, and an observant foe might later spot a hidden halfling or elf: “I see you behind that guard, you tricksy halfling!”
However, this
still doesn't detail how the DM should rule about
repeat hiding in the same spot. I have no problem with a Rogue being tricky in combat, dashing behind different people and disappearing from view from most of them by hiding with Naturally Stealthy. When the same character stands behind one character and hides, and then next round leans out, shoots, and hides again without moving, and plans to do the same thing on subsequent turns expecting the same results, then my credulity is stretched fairly thin. Even if the character were concealed by
improved invisibility, remaining in the same spot and making the same attack is going to get quite predictable.
