When playing a Summon Necromancer, I often feel like there’s nothing appropriate to use for the left-click skill.
Since all the skill points are invested into summoning, there’s usually no room left for bone or poison skills.
So instead, how about giving the Necromancer a basic skill that can be used for the left-click slot?
Personally, I think it would be great to have something like a command to direct summoned units — similar to the attack command in StarCraft.
