Boulder overranged rotation

Hi! At first, wanna tell thank you guys for your awesome game. Just wanna ask, are there any way to fix problem, where boulders with new unique amulet just overcomes close enemies in range. It works with big model Bosses, but just dont work with elites and usual mobs with a tiny model. Maybe there any way to make them rotate much more closer to character model? Thx for ur attention!
