meh the stacks are one reason to get it but when playing jungle my goal is always get the next safest objective. So i'll kill herald once the first dragon is killed (or instead of dragon if we have no chance of contesting it, it's a better option than going to farm my own camps anyway)
I can usually get my team or at least one laner to get a turret quickly with my help and the buff. or depending on the health of us/when we back I basically give my laner a giant sign saying "Come on, kill me i'm here kill meeeee" which gives the perfect opportunity to counter gank, get kills, and THEN get a turret. So I'm still going to go for it. It's very underrated and as long as you watch the laner's back from ganks they usually get some advantage in their lane because of the stats it gives (especially the movement speed allows your midlane to roam better)
