Guild Wars 2

Is it normal for this to happen as i do not remember this to be the case. Normally soothing mist heals for 587 and not 329. Seems to be odd post update. tested on both Rev player and thief same deal on both occasions. To conclude the soothing mist totals should be the same on all three times that it heals a low health player. Please may we have some confirmation on this from Anet.
