Weapon Charms are already fluff… thanks whatever game did this first for making this a thing (sarcasm if you can’t tell).
But aside from that, what the hell are ‘Souvenirs’!? What does this provide virtually - we know it’s not a charm, player icon, or any of the base OW1 item categories. Is this literally just a NFT to stare at?
Some people actually like them, ow2 isn’t just catered towards you 
What are nameplates?
What are titles?
so many questions
Its really wierd, i mean i do collect useless junk in games (warframe, if you played you know what i mean when i say ship decorations)
But i dont see use for it in game like overwatch from name alone…
Title i assume somethign like in paladins where under your avatar icon in game or in profile there is text with title you picked that others can see.
Nameplates tho i have no idea.
