First of all, as a Vietnamese I'd like to thank you very much for your great efforts of making a Dai Viet faction but for the sake of historical accuracy: we didn't wear any heavy armor, especially the mongol-like ones here

Actually we had no heavy infantry, heavy cavalry at all

Also for the canon, was it a bit too soon to add canon to the game? and historically, we invented some canon ourselves quite long before the Europeans came.

I understand your enthusiasm of making a strong Dai Viet faction, no offense at all but it's a bit too much fantasy here I think ...
