It’ll likely be left as is, which is great. High latency however, isn’t the real issue here. It’s about Comparative latency. If player A moves away from player B, then player B moves to run after them, they can no longer reach them, if the distance is 1 between them. Player B won’t catch Player A, without movement skills. Player B uses a movement skill to reach player A. Player A uses a movement skill to regain a gap greater than 1. And so it goes on.
The question therefore is, what is a fair, equitable, reasonable distance, that would allow a melee player to attack a ranged player, or a retreating melee player, before the distance is unfair, inequitable, unreasonable. Is more than 8 feet unfair? Considering ranged players can attack at ranges of 30+, a melee “Leeway” of 8 to 10 seems fine.
Consider a Hunter using Auto Shot. 8 to 35 feet is required. So if a melee player can get within 8 feet, their attacks no longer work. But if a hunter can maintain a distance of 12-35 (outside of what I have seen as a visual show of moving-Leeway on a Tauren with it’s larger hit box) then the Hunter can hit the Melee Tauren, but not visa versa. Note also the middle ground of 8 to 12, where they can attack one another, while moving. That in itself, makes sense.
Now consider a Frost Mage, Player A, that a Warrior, Player B just reached, by whatever means. Player B starts a rotation on Player A. Seeing it start, Player A casts Frost Nova, and Blinks away. Oh no, now Player B cannot hit Player A, and is now being hit by spells! But Frost Nova wears off, and Player B Charges back in. As Player A moves away. But due to Leeway, while Player B completes the charge where player A -was-, the attacks can still occur even though Player A has moved a short distance away. Now Player A has to move away again.
The smaller the Leeway, the less fair it is to melee players.
The larger the Leeway, the less fair it is to ranged players.
It is not about authenticity, because the authenticity is in and of itself required for smooth game play. The issue that is really being argued over, is not “should or should it not be implemented”, but in fact “what is the right amount of Leeway”.
