We don't sell syrups. We need them. Just compare it to the other Foraging lv10 professions. Botanist makes look like the devs made Tapper just for the lulz. You receive 50 more gold from maple syrups (which we really want for bee houses) and oak resin (the most useful from all syrups) gives more 37 gold when we are SELLING them, and we definitely don't want to sell them. To see how it's incredibly useless, even it DOUBLING the selling price of syrups wouldn't make up for the profession AT ALL. The benefits we get from USING a maple syrup are way more worth than extra 200 gold for selling it. The best way I see to improve this profession is to turn it to speed up syrup production, even for the same amount (-25% less time). That way it would be useful for keg makers and honey makers.
