I’m honestly surprised this hasn’t been fixed yet, but with the upcoming “balance” to hammer for warriors, I figure this would be a good time to fix it.
The issue: When casting Earthshaker on uneven terrain (i.e. a slope), you land in the air at the height of the highest point in the aoe. This often results in not hitting or affecting enemies below you.
Expected: Earthshaker lands you on the ground, stunning and damaging enemies in the aoe, no matter the height.
Please don’t turn this into a discussion about warrior balance; we have plenty of other threads for that.
