In-game Gems and the Items.
I am all about free stuff, but Anet need to make money some how. They offer sales frequently, and there is already a way of obtaining items for free: use in-game currency. Sure, gems are expensive now, but that’s to be expected by the influx of players. Save up some gold, and wait for the population to go quiet, and in turn, the prices of gems will go down as well.
EDIT: Also, lets not forget that GW2 rewards you just for logging in every day. every WEEK you get a free Black Lion Goods Chest. Sure, getting outfits or make-over kits is very rare, but it still provides a lot of commonly used consumables. I have never bought transmutation charges (I have 80 stockpiled just from the daily), or mystic forge stones, or instant bank access, ect. All of those I have PLENTY of just from signing in every day.
