Guild Wars is over six years old and there are still things the Live Team or other programmers haven't bothered to fix or set straight. This list, which you can expand, I am sure, could be a small reminder of things that could help the aging game.
- The price of crafting items:
=> There is Linen, which costs 200 gold to craft + 5 Plant Fibers. Since you can buy Linen at half the price at the rare materials trader, why bother crafting? Solution: reduce the gold cost to 20, so you could make a small profit for selling.
=> There is a Lump of Charcoal, which costs 200 gold to craft + 10 Wood Planks. Again, why craft those, when you can buy them at a lower price from the trader. Solution: Same as with Linen
=> Bolt of Silk, which costs 200 gold to craft + 10 Cloth + 10 Dust. The most costly craft, but the cheapest item of the three with the trader. Solution: 20 gold + 5 Dust + 5 Dust would be a start.
- Chest running:
=> If you want to get the Treasure Hunter title, you have to chest run a few locations, because the number of chests is so limited in explorable areas (IIRC 5 is the max of chest spawns). If the number of chests are doubled, you could have the opportunity to open chests during "normal game play", e.g. questing or during a vanquish. The number is still limited by the number of keys or lock picks you can afford
=> Nightfall's hidden treasures; Reveal the secret already. How do the chests recharge? The quality of drops from those does degrade, but how? Knowing more about that could help checking the chests for drops.
- Upgrade items
=> Weapon upgrades selling for 25 gold is not worth salvaging, because the risk of breaking is too high if it is not a max item. Perhaps increasing the value to 50 or 75 would make it worth again.
- Skills & mechanics
=> Smiter's Boon; Yes! The nerf which turned into a GW proverb, was some sort of bankruptcy declaration of the balancers. Give that skill a PvP use again.
=> Exhaustion; This game mechanic for the Elementalists could have been used to buff the class (e.g. you gain 20% armor penetration while exhausted), but it has never been touched.
=> Offensive Ritualist's spirits are still too strong
=> Mesmer's received too much love, but nobody bothers to fix the damage done
=> Pet AI is still troublesome
