As a fellow summoning fan I support this post :) More generally, icons for all kinds of active buffs would be welcome in addition to summons.

Definitely agree with this post. Also, what is with the distance that minions stay away from the summoner? The Poison Golem and the Feeder Zombies stand way far back from you...like maybe 10m and the speed/response at which they follow the summoner seems wonky as well. Additionally, the timing involved before they become aggressive and attack seems off too, Maybe a solution for this would be like what Grim Dawn has with the Necromancer where the minions have a toggle for Defensive/Aggressive/Reactive for minion behavior?

Agreed.
Counter needed for all summoners.
Parasite needs to state how many mobs can be controlled
Zombie skill needs to update heath/damage numbers when you select the relevant skill bonus
Auras need to show for all buffs/debuffs. I want to know what that parasite minion is doing.
Base minion speed needs an increase, even without dashing etc I'm leaving then behind.
Overall I feel that summoners feel quite weak and they are more like summonable dots rather than a force.
