Yea, the game is a cake a walk if you hide, attack, hide. The enemies are too stupid to properly perceive the player and their perception field is too narrow. But even the stealth system has issues, detection is global and neutral/friendly creatures are able to break you out of stealth. 5e as a whole made magical gear common and a necessity to be able to play balanced, However Larian has made those far and few between and are "cursed" in the sense that they are detrimental as well.
