ArenaNet:Guild Wars 2 suggestions/Spawning system

Spawning system (Discussion)
As GW2 will be a persistant world, there has to be a respawn system. The idea is to have a base for every kind of creature in their area. Killed enemies respawn in this base and return to their patrol place. More advanced creatures (Corsair, Naga etc.) could have a kind of fortress or city, less advanced creatures (spiders, trolls) could have a small forest, a cave, or a nest where they respawn. Maybe this base could be captured in some sort of way, but this should be hard to do, and after a while these creatures will recapture the base. Or maybe they have 2 bases, and if they get overwhelmed in one base, they go to the other base. Or you totally drive them to a different area, so it actually has an effect, and every area will  have different creatures every time you enter. If this happens, there should be some system which says where you can find creatures, like a news NPC or a farmer which fled because a group of insects settled near his house. You could have some related quests, where people reward you for driving a group of creatures away. This could give some large rewards, so people who need money can do this instead of farming.


 * Why this is a good idea
 * Prevents spawning in the middle of a fight, where monsters may overwhelm players.
 * The bases mean more, and changing challenges for people.
 * More adding to the persistent part of GW2.
 * Having different creatures spawn every time you enter a map is a very good idea.
 * Players will not be able to repeatedly farm one single species.(ie: Those poor raptors).
 * Encourage players to join guild, if and when a "boss" type spawn, you'll only be able to get these information from guild and alliances members. I am pretty sure very few will quickly kill off the boss and return to the outpost and tells other players about it.


 * Why it may not work out
 * Might be hard to work out combined with creature-related quests.
 * Bad for players who absolutely do not want to join guild.

Fights between different creatures (Discussion)
This is based on ArenaNet:Guild Wars 2 suggestions/Spawning system. Have creatures who are unfriendly to each other fight each other for territory, by capturing the enemies base. This way, one specie can become powerful and rule over a large area. If these areas become too large, people can get quests to capture some of the bases, which are then captured by a different specie. This can yield some quick money/xp/faction. A specie which is driven from their last base will quickly get a new base, so creature-related quests can still be done. There will also be a map available with where you can find which creatures for those quests. The bases can also change depending on the race that owns it. (A human fortress can become a ruin with many tunnels when mandragor-like creatures capture it.)


 * Why this is a good idea
 * More interaction with and between the environment and creatures.
 * Adds to the persistent idea of GW2.
 * More realistic (if anyone cares).


 * Why it may not work out
 * Low rewards might mean it doesn't get enough attention, and some races who control a large area will control it for a long time.
