Zombie Ward: excellent new addition
I've seen quite a bit of excited discussion over new runes, and some negative about some specific runes, but no one seems to be that amped for Zombie Ward. This is EXACTLY the sort of thing I was hoping for with a new runes system, and this has the potential to really amp up the vision game. It's a small thing, especially when they are gonna add so many changes at once, but I really like the direction.
. Since it now can also provide situational, but usefull, vision (The cleared wards are normally in places where you would like to place wards yourself).
