Guild Wars 2

So all I have is a simple question related to the information below…

Major Rune of Sanctuary:
(1) +15 Vitality
(2) +10% Boon Duration
(3) +35 Vitality

Superior Rune of Sanctuary:
(1) +25 Vitality
(2) +20% Frozen Duration
(3) +50 Vitality

My main question is this.. how come the Major Rune of Sanctuary gives +10% Boon Duration but the Superior Rune of Sanctuary -DOES NOT- give +15% Boon Duration and instead gives +20% Frozen Duration?

Is it because of Superior Rune of Water and Superior Rune of Monk? Does Arenanet not want us to have that +45% Boon Duration with all of those runes?

I mean, Major Rune of Sanctuary is still +10% Boon Duration, so in general I can get +40% Boon Duration on my character. Is this a small bug with Superior Rune of Sanctuary? I know it’s only 5% less Boon Duration, but I would like to know if it really is something that needs to be fixed, I wouldn’t mind an extra +5% Boon Duration and also that extra Vitality that comes with it.

Please, give me some feedback, anyone who uses the +% Boon Duration runes and such.

Giving this a bump, it might also be in the wrong forum but I had to start somewhere.

I have the same exact question. It seems like this is a game bug or at least a description bug. Have you tested the Superior Rune of Sanctuary to see if it actually increases Freeze Duration by 20% or does it increase Boon duration by 15%?
