This same person has specifically told us in previous videos that "shields are
not weapons." HOWEVER, this is from the Wiki, today:
"Shields are a type of weapon in Ashes of Creation."

There's a WHOLE super-thread on why no dual-shields (
yours truly /Support's dual shields!) - but why not something akin to spiked dueling shields? Maybe even just as a cosmetic weapon that covers a two-handed sword/greatsword?

It'd play into a fantasy genre of specialty/novelty weapon, and would create a market for a new type of item to obtain in-game or via cosmetics. There's a whole realm of different shapes and coloring/sub-features that could go along with them that we could seek out, while collecting different weapon types/weapon covers for our toons' arsenals.
