Guild War maps have a list of every single zone. These maps also are very detailed showing all the mobs in a zone and where they are, where chests spawn and where quests take place at. This makes things much easier and easy to find certain objects. More maps are always being updated and more points of interest are added as well.

Here is an example of Guild Wars Map GW Maps Information submitted by our community.  (Note this information is not valid and should be considered nerfed)

There is a bug in the skills Thunderclap that allows you to keep knocking the player down and every foe around that player even when your mana reaches zero; usually Thunderclap would take something like 7-8 Mana off when you used it until your mana got to 0 in which case it would run off, but now you can keep it up. A W/E works best for this because you can cast Thunderclap and then just use a schockin sword hilt and you will knock down foe constantly.
