What I am proposing is to be able to use Detonate Dead on Summoned Zombies and Skeletons both as a more offensive skill for a pure summoner and as a possibility for zombies and skeletons to be used on other non summoner builds. This would give more range to summoners and also give Detonate Dead, Summon Zombies, and Summon Skeletons more use to other classes.
There would not need to be an added downside to Detonate Dead either because Detonate Dead does 20% of the minions max life and Minion Instability does 33% of the minions max life. This means that there would not be any imbalance issues with minion life and detonate dead.
I'm not quite sure of the technical aspects of making this happe
