Oh I know they definitely are but when compiling this list we need to thing of how often something on the forum is used in that context as opposed to the regular context.
Let’s take “bracer” for example.
How often would you find someone using it under the RotMG context here as opposed to the normal definition of “something to bind”? You’d definitely see it more under the RotMG context.
So that’s a worthwhile abbreviation.
Now let’s look at “1”.
Under the RotMG context it’s a quick single message in a dungeon. How often does that need to be pointed out in a forum post? You’d definitely find people using it for counting anything else a lot more often here.
You’d probably confuse more people with:
I’ve only ever seen 2* white bags.
* Def+vit from Malphas, or def+dex from Limon
Tl;dr: We need to remember that this isn’t a glossary of RotMG slang you’d find in a wiki. This is hovertext to explain slang as people post on the forum.
