The proc gives (at best, at ilvl 795) 43,7% damage increase for 15 seconds for everyone in the raid. It also has a 120 second (2 minutes) cooldown. That equals to an overall "buff" of around 3.5% damage (and healing? I don't recall the proc they have) to the whole group over the duration of a fight. Let's say it's used during burn phases and everything, it will probably be a 5% buff. It's not insane, but it is a slight progression buff.
