Thanks for the work-through, but switch your numbers around - Sightstone gives 100 health, so 250 gold for that.

700-250=450, 450/75=6

So you only have to drop 6 wards for this thing to be cost-efficient...nice!

I don't usually math things out with this game - it doesn't tend to help obsessing over numbers in the other games that I play (WH40K and M:tG), so I wasn't even thinking about that. Still, if I'm only dropping 6 wards in a game with this thing, I'm really slacking off....
