Level Your Tradeskill Faster
Have you hit that 190 mark on Leathercrafting or Blacksmithing and getting it up to gain your next armor kick recipe a bit painful? No problem! If you're willing to spend the gold you can always level them up at your Faction's capital city.
If you're purchasing correctly, you can easily level your tradeskill up 30-50 points in as little as 10 gold (at around level 40) in an hour or two by purchasing raw materials from the trade channel. Sure, 10 gold may be a decent bit of change but if it saves you 2 days of playing time to find all the ingredients you've purchased, it may be a bargain.
So buy those mats and get up to the sweet spot of 250 on your tradeskill a little faster. It sure is nice to have use for the armor that you're crafting.
