If there is a ranger class in 5E, how do you want to see the ranger's fighting style handled?
Since at least 2E, and further refined in 3E and 4E, the ranger became "the class" whose fighting niche was two-weapon fighting or archery.
I'd like to see the 5E Ranger have a more flexible style, but at the same time not step on the fighter's toes as "the best with a weapon". If possible, I'd like to see the ranger focus on one fighting track and be fairly good at it - whether sword & board, two weapon, two-handed weapon, hurled, archery or even crossbows. The ranger should be good at one - maybe two styles by later levels.
The converse would be the fighter is GREAT with any weapon; the ranger *might* be able to match the fighter in one style, but the fighter is visibly superior overall.
