How do i make the WoC monsters not spawn?

I already abandoned every woc quest but when i go to explorable area, there is still woc monsters. Some bosses doesnt spawn when those monsters are there .

You can't make them stop spawning (at least not at the moment). It might be that the future parts of Winds of change will reset the spawns, but thats up to Anet and unknown at the moment.

If you need a specifick skill of one of the bosses, as far a I know there are replacement bosses for all of the skills, so you can still capture all skills in the game.

As far as i can see the only way of removing woc spawns is not to finish factions but even that has a flaw.If a team has woc enabled except 1 chr who isnt woc enabled - the spawns dont revert - its different to wik.
Hopefully anet will sort this out as im safe assuming its annoying many of us gw players.

quote from Wiki:

so until the woc stuff comes to an end...(at which time they might change it like they did when you finished wik--we hope)...you are stuck with them.

well actually if you have the 15 attribute quest from zunnra, the enemies dont spawn in zen daujin.

other then that i dont think there's any way to not make them spawn.

This is ArenaNet's stance from the support forums.

Anets stance doesnt state they are going to fix the spawns for non woc chrs in a team.
I might be tempted and put on their forum a question about woc foe spawns with a non woc chr in team as it will cause endless problems - i can see players wanting to vq and rejecting any players with woc not enabled.
Does actually make you wonder what anets testers do - you cant say to me none of them noticed the major flaw - oh look i can bring a non woc chr into party and be able to farm woc foes etc.

It's only your opinion that it's a "major flaw". To me it is simply a fact, and a relatively meaningless one at that.
