The issue is that stealth and initiative (and shove, Hide, etc) are basic, core mechanics of D&D and BG3. If the only way to use them is through BG3's OP implementations (shove from stealth=100% success, heavily armored characters don't roll stealth checks unless they enter enemy line of sight, the game gives you 2 free surprise rounds, enemies often don't search for hidden characters), then I as a player, must either:
- (ab)use these mechanics and feel like I'm cheesing the game, or
- manually choose when to self sabotage myself to compensate for the OP abilities, or
- avoid that mechanic (and thus entire playstyles) entirely
If you don't want to use an OP mechanic, then neither of the other two remaining options is good or enjoyable gameplay.
