Guess Dark Harvest Isn't "Fixed" on ARAM

with Dark Harvest. with only 86 stacks (level 11 at the time). She throws her shield doing over 1/3, almost 1/2 (if she crit) of the champs health in one hit. Yes, I get that having the spellblade activate on Trinity adds damage and the crit helps too, but the fact she only had 167 damage with Trintiy and Rapid Fire, 86 stacks of Dark Harvest, and took me from 728 to 123 in one hit seems like Dark Harvest hasn't been fixed much. Not to mention she also had no tank runes at all yet she could tank multiple tower hits; doesn't seem very balanced.
