You keep arguing like this is "High Fantasy" where Goblins are the generic enemy, it isn't, this is Tinkerers universe, where Goblins are our Friends/Family & Cum Buckets. Failing to account for the world you live in and continuing to use outdated definitions marks you as a racist against goblins.
Irrelevant, the argument was about having too many short characters, not their origin.
There are too many human sized characters IMO

What worthwhile difference is there between Mia, Beth and Gwen?
Maybe I misread something but wasn't it clearly stated that she was the MC's Half sister, that they did not have the same mother.
The other stuff about her was, what is known in the trade as "being cute"

"Tongue in cheek"

, "Not being serious"
I'm sure you will, shame you misread the map and are currently fighting on a completely different hill... Who is it you're fighting BTW

Is it Dwarfs??
I don't see why we can't have both Gnomes and Dwarfs. (and Halflings, Imps, Goblins, Midget Elves, Pixies, Fairies,...)
