I use this skill extensively and for me it's by far the best skill that the QoT has. It can be used to farm experience and gold at a second lane and the heal is quite a lot at level15, enabling you to play the tank of your team. However, to use it efficiently you have to micro-manage your shamblers a lot, which can be a pain in the ass, especially in the endgame where you can't find your shamblers to mulch amongst all the other units. I would really like to be able to double-tap the skill key so that the QoT would mulch a random/nearest/lowest health shambler.

Anyways, in my ~130 games I only saw maybe 3 other QoTs using that skill, I guess because most players go open form to use her area-of-effect skills. Getting Demigod kills with the damage of mulching is quite rare, but really really cool.

I highly agree with the autotarget suggestion.

Abilities that target demigods are harder to use in a crush because they stand out and you get a key to help oyut arget them. But abilities that target minions can be very frustrating in dense battles.

my current build with qot atm is just shield, ground spikes and spike wave. everything else i find rather useless or just time/mana wasting.
