And as i've said, this is a OPTIONAL thing. IF you wanna archers unable to hit your fighter at 14m, don't play with this option. Have fun with useless ranged classes. Not only archers. Sorcerers/Wizards/Warlock already only start to shine at lv 6+ and the lv cap will gonna be 10. Once you finally get your fireball, you will only be able to hit enemies at CQB(Where the spell is useless and often deal a lot of collateral damage)
Just a note: The word "option" is not magic, and using the word "option" does not mean something which radically changes the rules of gameplay becomes trivially easy to design, test, and implement.
I guarantee you that the game is not going to have two sets of maps and rules for ranges based on whether you select the "shoot from infinity" "option". The developers are going to design the combat arenas in one way, taking into account the ranges of spells and attacks.
The range they use should be long enough to cover an entire combat arena if possible (unless the arena is larger than the PnP range), but they'll probably want to avoid situations where your team can go "all long range" and arrow or cantrip every enemy to death before they can close to attack range. The reason is because an optimum combat strategy which is boring, repetitive, and too easy is not good design.
