I'm just saying I personally don't like it. I'm not saying to remove it, just make it optional. I'm not familiar with D&D rules. It's all made up anyway, isn't it?
In general I think the more options a game has to configure how it works, the better. Ie - you already have difficulty levels. So if there could just be a checkbox to on/off other game features that would great. Provided it's not rocket science to implement.
Something you may not be noticing is that the enemies are missing you just as often, assuming no advantage/disadvantage modifiers. Would you want that checkbox option to turn off missed attacks if it applies to enemies also? If not, it's a player exploit and would unbalance the game.
It sounds like you're just not familiar with the D&D systems yet, which does take a while to get used to if you've never seen it before. In particular, you need to pay attention to the Advantage-Disadvantage mechanic for "facing" and height difference, which can have a big impact on hit chance.
