Though the OP may be discourteous, they illustrate an interesting new-player experience.
With no prior 5e knowledge, they didn’t know what went into calculating hit chance. They tried things out until they found the low hanging cheese of hiding every turn for free, whereupon they destroyed their own fun.
This is a great example of the dangers of the current hiding system. When the game teaches new players (as early as the tutorial) that hiding gives a huge boost with no opportunity cost, that’s what the game becomes about.
