An idea to buff the Vietnamese: -75 Wood cost for building Archery Ranges

The Vietnamese have long had a poor winrate in both 1v1 and team games, mainly due to their lack of economic bonuses, predictable builds, and their bonuses not lending themselves well to early-game. The extra HP on their archers, for instance, doesn't help them against skirmishers, which will still take them out easily.

One idea I had to buff the Vietnamese would be to give them a discount on building Archery Ranges. -75 Wood per Archery Range would be a nice boost for their early-game archers and their late-game archers by letting them save a little Wood. It wouldn't be nearly as strong as, say, the Huns' "no houses" bonus or the Teuton's cheaper Farms, but it'd still be undoubtedly helpful without putting them over the top. It'd still be fairly predictable that the Vietnamese would be going for archers, but they would at least be able to save some wood when going for them.
