[Gameplay Bug] Hecarim's Devastating Charge sending enemies in random directions

I am seriously tired of this. At least 1-2 out of every 4 times I use the move the target either goes sideways at a 90 degree angle, doesn't move at all, or (rarely) is knocked behind me. The move is supposed to move the target directly away from Hecarim and since he is moving forward to should only really take them along the same path. However for months the move has just been doing whatever it pleases.

Considering this is part of Hecarim's main combination, please address this.
