Terrible analogy.

Terrible analogy.
When we have less attacks per round, the monsters also have less HP, so the static +2 damage means more. For the extreme case, let's look at level 1. Instead of an Ancient Red Dragon, we'll use a Zombie, which has AC 8 and 22 HP. our longsword attack deals 9.5 (1d8+5) damage with Dueling and 7.5 without, we have +5 to hit, so we hit on a 3 (90% chance). We're doing 8.55 average damage per round with dueling, and 6.75 without, which means we'll need 2.57 rounds to kill the zombie with dueling and 3.25 rounds without. The Zombie has +3 to hit and deals 4.5 damage on a hit, which means if we had AC 14 its DPR would be 2.25, while is we had AC 15 (from Defense) its DPR would be 2.025. In other words, Dueling Style would save us 2.25 damage (from the one round the zombie isn't attacking us), where Defense Style would save us 0.9 damage.
I would still keep the bow and use it when the flying creatures attack or for several rounds before melee range.

Why?
I dislike specific weapon styles. Actually let me clarify. I like crunching them and using them to come up with interesting builds and trying to figure out which is better and being pleasantly surprised when I realize one I discounted is useful for something. But while I like them for character building I dislike them in play, in character concept etc. Once you include styles and choose one then you have suddenly declared that your fighter can only ever excel at one style. I like fighters that can excel with a broader range of weapons and so I dislike weapon based styles.
If you deal an average of 20 damage and hit 90% of the time what is the number of rounds a 1 hp creature will last on average? 1.11 rounds
When you aren't looking at 100% chance to hit even the question of the expected average number of rounds a creature will last is a lot more complicated.
In which case it doesn't match the longsword and greataxe example where we have a clear differentiation of them in the game world regardless of any written down mechanics around them.
One may could even chop a tree down with the battleaxe but probably would be denied doing so with the long sword.
Weapon styles should be included with proficiency.
Weapon styles as presented in D&D are terribly boring but that is another kettle of fish.
Okay, but by far the most common thing that DnD characters use their weapons for is attacking with them, and as far as attacking with the weapons is concerned, there is no differentiation between the longsword and the battleaxe. Yes they're called different things, yes they look different, yes they represent different things in our world, but in combat in the world of DnD, they are identical. One thing I know about Longswords and Battleaxes from the real world is that wielding one of them feels different than wielding another, but in DnD, they feel the same to use in a way that say, daggers, don't. Because daggers have different mechanics in the game that evoke the feeling of wielding daggers.

For fighters yes, but Paladins and Rangers not so much.
