Guild Wars 2

So I tried to do some research but it just seems most people are guessing or not sure.

Ive been using pots for a long time but only recently started questioning when and where they are working, few examples.

HOTW – I drink sons of svanir, then proceed to see a ton of icebrood during dungeon, does it work on these? Even the 2 quaggan guarding that one boss are considered icebrood.

Some say that the whole dungeon is considered svanir, but then lets look at SE path 1? Its all inquest….should we drink inquest pot or does anet make entire dungeon work for dredge?

Last example – COE, no inquest in sight, lots of undead, but also at start is ice golems considered icebrood…..

I WANT TO USE POTIONS, but…if they only work half the time, i might just scrap the idea and use old boring sharpening stones.

Potions were bugged so that you took extra incoming damage instead of less. It would be nice to know if that had been fixed yet, presumably not.
