Memory Leak
It’s not a leak ,Gw2 is just able to use up alot of memory and when viewing Gw2.exe in CFF explorer you can see that “App can handle 2>gb adresses space” is enabled,meaning gw2 can use over 2gb of memory.
A memory leak is not the same as using a lot of memory. Memory leaks mean that the software in question will continue to use more and more memory the longer it runs – having a usual/stable amount of memory use (2.2gb in your case) means that a memory leak is not present.
Chances are you have your texture settings higher than your guild members – textures are the some of the largest assets games use and can take up substantial amounts of memory. This means that your graphics settings are higher than your guild members’ – and experience on my server (never mind my guild) has shown that Guild Wars 2 becomes more unstable the higher your graphics settings are.
Lower your graphics settings. See if it improves.
