Guild Wars 2

Glyph of Elemental Power: The trigger chance of this ability has been increased from 25% to 100%. Weakness duration has been reduced from 6 seconds to 3 seconds. Internal cooldown can now be shared between elementalists. This ability will no longer apply conditions to nonenemies.

So, I want to ask what is the meaning of this line; what is the internal cooldown of GoEP for a single person? and for two? This is important because, within one day of the patch, my guild was already stacking tempests to smoothly finish off raids by accumulating absurd amounts of burning damage (I don’t think this condition was intended to stack past 50 or so ticks at once outside of world bosses?). Now, I do have a tempest and I do like playing it, but if GoEP is not bugged that seems pretty game breaking to me. Perhaps not much on WvW because other sources of damage and CC would obliterate a full tempest zerg, but elsewhere? Say goodbye to your necros, thieves, etc. because anything will quite literally melt in front of a couple tempests.
