In addition to nerfing Dark Harvest, you might want to buff turrets' resistances further.

I played a few matches last night in the current Dark Harvest meta, and yeah, it's quite nutty right now, but also I noticed that despite the focus you guys put in outer turrets being resistant, they still fall pretty easily should the lane push in, and in addition to that, they give quite the gold amount.

So, yeah, also I accidentally pressed enter and this thing posted, so here's hoping I edited it before anyone clicked.
