This is my list of things which I’d like to see in the game. It is a bit long and chaotic, but I guess there are some valid wishes in there. Probably I’ll add some more later. 
Better separation of Casual and Hardcore gamers
There is always problem during events, that the more Casual people (people who don’t/can’t play as much due to various reasons) have minimal chance to get any good rewards. It should be encouraged that with little play they can improve themselves as well.
Add new PvE chapters other than the prologue
There were plenty of huge PvE events already, they should become Chapter 1-x after the Prologue.
Ability to reset Prologue
So the players would play them again. For example you could reset the Prologue every 3 months.
Add windows features for windows version
Mouse wheel should be used to scroll long lists
No command input until release of mouse button. So if you keep the button pressed, don’t make swaps by moving the mouse.
Achievements
Not stupid ones, like you “finished a chapter”. Instead come up with good ones, which really feel like an achievement and it is not just a milestone during play, which you would reach anyway. Funny achievements are also welcomed.
Ways to get desired covers
A way to buy desired character with specific color AND
A way to work a lot for it and get it for free
At the moment we can only get the desired covers from events. But since there are so many characters, and so few events with character loots, it is a very weak way to get them. For example I didn’t see any covers for Loki, Patch or OBW since over a month. During that time I used up at least 100 1 and 2 star tokens, got 2 OBWs, but with the wrong skill. So the characters I’d like to improve are not going anywhere.
Compensation for the losses caused by cheaters
When I lose position and so better reward because of cheaters, I’m kind of annoyed. There was an event where I saw 4 very suspicious players in the top10 with me, where 1 position can mean a whole different reward. Ofc the best would be to prevent cheating altogether.
Separate Identical enemies
When there are identical enemies, give us a way to see which countdown belongs to which enemy.
This is especially important with these high damage guys, like HAMMER Snipers. The entire match can depend on stunning the correct enemy.
Let the enemy HP go under 0
It is very satisfactory to see how much damage we cause to them with the last hit.
Remove Skip tax
The players have several reasons to skip, chief among them is the low reward points.
Improve sell value
For a level 85 character we get back 12500 Iso. To level the character to 85, we need almost 70000. We earned all those Iso, why do you take it away?
Proper respec
Whenever the devs change a character’s skills, the player should get back all the covers which build up the character and all the used up iso. For example an 1/0/4 character would become 5 covers and the used Iso. (of course this would happen when he logs in, so if he is away for a week, he won’t lose the covers) This way the player could decide if he/she wants to play this character at all.
Level to max button
A feature to gain multiple levels. The game would ask if you really want to spend x Iso to level the character to y. (Of course x and y depends on the actual Iso reserves and the available levels. Then when answered with Yes, the character would level up. It would spare a lot of time when the player adds multiple levels, especially with higher level characters.
See final ranks
I want to see which exact position did I finish. I also want to see my immediate opponents above and below me and the top 10. Basically the lists which we can see during the events.
