Is cull, from a money stance, worth buying
So I was looking at Cull, and i have been seeing pro players get it on first back during lane swap scenarios where they will use it to get a bit more money a bit faster. But if you look at the price it costs 450 gold, whenever you kill a minion it gives you +1 gold up to 100 gold and then it gives you +350 gold when you finish it and that totals the gold that it gives right back to 450 gold. Its only worth 180 so you really only prophet 180 gold and thats after you buy it, finish its stacks and sell it. So my question is, from a money stand point is cull worth it?
