Commonly found in most RPG's and basically any other game, waypoints are a pin point on a map to show you where you need to go without scrambling through your map. Now, waypoints are more helpful when you have a mini map on screen. We can not implement a mini map due to the interface and to the fact there is no room, unless they tinker with the interface of course. The solution to that could be a arrow at the feet of your character (bare with me this could be kind of hard to explain).
Arrow pointing to destination: ← →
You: ✺
← ✺ →
In the diagram above (birds eye view) it is showing how the arrows will be pointing, however, there will only be one arrow pointing in that direction you in need to be going and it goes in a 360 digress diameter.
This can be helpful in a couple of ways. You are not having to open up your map covering the screen, then closing waking up to death (in other word, you were killed when looking at map). This happens to everyone. Also it is just faster and save a great deal of time. I know some of you sarcastic like fellows are probably saying "Well I know where everything is so I don't need even the map", or "Just go to a safe place and look at the map." This is true, but some people who are new to the game or not great experienced (trying not to define them as noobs, well just kind of did :/ sorry peeps who fall under that category, no intention to be mean) may not know these things giving them a shortcut and a easy tool for them to use.
If any questions or good add-ons please comment (be constructive and not destructive please, I would like to go to bed in a dry bed instead of one filled with tears of misery)
