for the first thing i want to apologize for my crap english.
that game is nice, and im just want to make it even better. may be im not so good tester but here is some ideas for improvement and some (imho) bugs.

1  id like to see really helpful tooltips for summon mob skills. livor mortis and both swarms. there is nothing just HP of mobs. btw even this info lie or just some passive skills and perks dont work. sometimes u pick +HP perk and tooltip said that nothing changed. i wonder to see how much my summons have critical chance ( if they have ) how much is that critical damage (% of inc damage) how much is it attack speed. how much is it attack power. numbers, u know ^^. some skills say - "increases damage of the summon" like first perk of  feeding swarm spell. is it all summons of just seeding swarm ? how much is it increse. how much is it was ? how much is it now ? alot of questions - poor info. plz just can u make tooltips full with final numbers consider all skills-spells-passives-items what change current summon stats

2 id like to see summons hp bar. like u can switch on-off party players HP bars. and can u make it other color than red plz ?

3 id like to see summons damage. i can switch on-off own damage numbers. but i cant even know how much they are hits.

4 is it fine or it is a bug ? if u trying to cast "parasite" to friendly target like own summons (missclicks) u start to drain own health. i have not hause of leeches perk on it for sure

5 is itfine or its a bug - i cant target hauntingstones and same structures with parasite. summons wont attack it neither.

6 i have faith leech passive (leeching shield instead of health) and each time when i start to cast something. each damage tick of parasite for eg. my damage shield drops down and start to fill again and again. even if noone attacks me. same things with plagueburst skill.

7 Toxic Emanations passive. it is work each reconnect to the game. but stop work shorts. sometimes it is stop after my death-revive. sometimes after change levels of map. i cant say for sure but it isnt work well for sure. i can see working aura just 2-3 mins after connect.

8 when i use aspect of apocalypse my summons died really fast. i think that happence bcoz of sacrifice of flesh passive stop work. is it fine ? just want to let u know.

9 parasite spell. controlled mobs. if i have a nice mob already - i cant use that spell for damage others. bcoz mobs will change to new ones. wonder to have some way to keep a mob and dont re-summon each time a new one if i like my current summon. may be paragraph 10 of my comments can do that?

10 id like to see how much summons i have. if u have 3 archers + 3 melee + golem + parasite controlled mob it isnt so easy to know - are they all alive ? may be some kind of buff-like bar ? or add it to party screen at left side ? and id like to have a way to dismiss some summons by mouse click on it icon.

11 parasite controlled mobs. i wonder to see - what AOE skills is a friendly (from my summons) and what skills are not. atm both kind of skills make a red area at the ground. may be we can make friendly spells other color ? like green.

as i said im just to trying to make the game better.
