str support "skittering stones"

hey, i hope i didnt missspelled the supports name, the one that summons minions if enemies die near earthen destructable created objects like earthshatter.

question is: am i to stupid to make it work or did ggg released with it the just most useless skill ever? like it is totaly useless in bosses already as enemies have to die around earthshatter, shieldwall or the new hammer skill, wich usualy dont exist in bosses, so making a build dedicated to it already useless for bossing in it self.

but once again. maybe i am just to dense to make it work, so what is you guys experience with it?

I'm assuming you're still in the campaign cause you're trying to use a pack clear skill for single target..... yes there are skills that are good for clearing that suck for bosses. You wouldn't use them for single target obviously...... it's not rocket science. Like unearth for summoners is great for clearing maps but useless for single target.
