I like the summons. For 10e, they can do ~40 damage every few seconds, take some fire, and spread conditions- better if you give a hero Epidemic. Ice imp has AoE, too. I use the Naga with my weakness-casting Necro which provides constant knockdowns (good for beating Magni - another pointless minigame). I took my necro through Factions recently. Since it was my first time, I watched the cinematics. I usually had a summon up for the mission ends, so during the scenes where the NPCs are telling me how brave and powerful I am (lol), my Naga would expire with a death hiss and a face plant. It's pretty funny to see.
