First off how did you manage to get -21 posts xD.
Now to the Point:
Infinite Stealth and TL created a lot of problems what you already said for example, Scouting what only is good in pro, etc etc. basically it makes her Strong in Pro level play (but it made her 100 times more boring to watch because you can’t even hear them calling out what they are scouting) but It kept her almost trash anywhere lower GM (In which she always had a pretty good Winrate.)
I don’t think it will be possible for the Devs to balance her to more Rank’s without removing it.
But I don’t think they like reverting I hope they find another Solution…
If you want to go deeper into this Topic I have a whole post about it:
