I'd rather keep stealth as a valid gameplay option, but nerf it.
Honestly, there are worse ways to cheese at Level 2-4 than stealth. All you need is a portable explosive barrel and Astarion's fire arrow cantrip.
I threw a single barrel on the first pack of gnolls. Dead. All dead. Instantly. Portable fire ball at command. 3 barrels can decimate about anything, anywhere.
What gets me is that stealth is not fun to play. Too clunky. If the entire party has it, "surprised" needs to be changed to a mere boost to your Initiative.
Enemies also can't be sitting ducks. They need some way to locate you, not skip all their turns. They already do that just fine outside turn based combat 🙁
