Silly question about Relic +1

[bluerei]

I personally don't like the idea of tagging +1 at the end of an item, or +2 or +3

HQ symbol is nice, but the + stuff sounds a little bit tacky?
To me anyway

So I was wondering, why would it be called +1, and not or completely different, much like AF and AF2. Or just to have a a slight addition to the name to make it seem cooler?

you guys complain about the dumbest of things. A replacement name to make it "seem cooler" isn't gonna affect anything in game. They could call it a "poop-covered stick+0" for all I care.
