Dark Harvest.

This rune is hilariously broken right now on the PBE. If it goes and hits our live servers in this state it will completely snuff out most damage runes, being a strong generalist and “win more” type of reward.

Dark Harvest users on a good game get nearly 4-5k damage on average from it. Dark Harvest is also incredibly difficult to deal with as well because there’s very little counterplsy towards it other than “don’t be under 50% HP. It’s dark Harvest user starts snowballing you might as well FF.
