Guild Wars 2

As the title suggests,
there is a Problem with the Poison fields, in some cases the fields are really hard to see, especially under water, sometimes you only see a very small part of the border (where it is not underwater), so basically u see almost nothing of the poison-circle.
Once u realize u are in a poison field, its too late sometimes.
It would be nice to fix this by making the borders bigger or something like that.

And then there is a “problem” with the graphics option “reflection”.
Having a rather middle-class PC (4GB Memory, Phenom II 9600, geforce 460 gtx cyclone), I need to turn everything to low at Tequatl.
2 Options that give you a Huge Performance Boost are turning off shadows and reflections.
Now the problem of Tequatl is when i turn of reflections, the water starts glowing so bright that i cant focus anything else due to the pure brightness, so i have to stick to using “terrain and sky”.
So is there a way turning it off, and getting performance, without the water starting to glow like this?

Turning off post-processing should take care of the glow i suspect, as most likely that is bloom.
