I love positional skills. Personally I wish they would add more of them, we already have 2 charges of true north so that's pretty good for moments where you can't hit a positional. For reaper it almost lets you hit every positional without actually positioning too much.

It would honestly be awesome if Viper had a positional on every ability, though I'm sure it won't.

Positionals make melee more fun to play and diversify it from ranged. If I were to flip the situation and say "I wish they would add positionals to Ranged, and remove all cast times from the game" People wouldn't like that very much. Different playstyles interest different people, some people like standing there just hitting the button, some people like doing that but having a cast time, and some people like being right up close the monster and moving around to deal a bit extra damage.

I don't want them to make casters and ranged more like melee, I just don't play those jobs that often, every job doesn't have to be for every person. It's good to have some kind of uniqueness to them, even if I don't personally like the thing that makes them unique (casting, standing still) much.

There's no need to simplify things any further just to make the difference between ranged and melee be how far they are from the boss.
