It was really fun! My warlock followed a somewhat recent build posted on this forum, focused on casting fire spells
(exept it is a blood mage/berserker and not an evoker/berserker), so maybe it wasn´t well adjusted to melee dmg (and I suck at adjusting equipment and buffs xD), but it does push the enemy easily to the carnage zone of the hit itself, and ONCE i managed to push back one of my clone's targets back, and it was woth it
