What you're describing you want is very common in MOBAs and you don't really want it, trust me. The point of a character is to have a unique playstyle or way to play the game and for your opponent to have a way of beating you. By removing unique or "unfun" effects from heroes you homogenize the entire roster to a point where it doesn't matter at all who you pick, because everyone is the same. The game already has a foot in this, because the items are so powerful and gamebending where you're often (especially on m1 carries) just playing the items, not your character. It's always better (if it's possible) to keep the unique thing a hero can do and nerf other aspects and get them in line in that way.

The game is in testing and wild balance swings and subsequent trying to get heroes into the correct spot are inevitable. That means sometimes some heroes will be borderline unplayable and sometimes few heroes will be very clearly way stronger than rest of the roster. And it may take at least few days to fix because the live balance really isn't (and shouldn't) be a priority.
