I feel very apprehensive about this kind of house rule. I think a similar effect can be achieved purely by lowering the DC on a few of the checks in the game because I don't think the issue is that players don't have enough bonuses, but that the DC for certain skill checks feels off. Similar with AC, many of the enemies we face at our level have a fairly high AC because a lot of them are not meant to be encountered at our level.
Player's don't have a lot of bonuses in D&D if I'm not wrong (except items, bless and ofc characters build).
I'm not sure it's ok to only have specific bonuses in a video game and the concept of advantage (D&D) is not easy to play with. You have to use very specific mechanics which require a good knowledge of the spells, abilities and mechanics.
Players have to find ways to improve their %to hit but new players when they'll start a game for the first time won't know why faery fire, bless and even their modifiers are REALLY important.
According to me it's a very good solution to add
a few easier bonuses but ofc things have to be balanced.
But maybe there are things I don't think about.
