Probably not the answer you’re looking for, but honestly if 3rd gives you such an advantage, I don’t see why it shouldn’t have this downside too.
Well, it gives ME an advantage, but that is not necessarily true for everyone. Most of my friends hate playing in third person - but I feel like if the game is going to offer both they should both be on a similar level of usefulness. Not being able to fight near walls in third person without going completely blind at times just doesn’t make a lot of sense to me.
