Would have to agree. Since the top range from the weapon in Play Test #1 is 60ft. So, a melee focused player can reach the ranged player in 2-Actions. Then still has an attack action, which probably will do more damage than the ranged weapon.
Let's just look at the scatter gun (real life shotgun). It has a comfortable hunting range of 40 yards, which is 120ft. A melee character would not be able to reach the range player in 1 round. In Field Test #1 the scatter gun has a range of 15ft, or 5yds, which puts you in reach with a single stride action, and has the unwieldy trait. So, unless you take the feat it is just 1 attack for 2-actions. Unless the enemy has an ability that is activated by being adjacent to its allies. Would say you are only going to get a single enemy in the effected area. You might get more damage from taking the multiple attack penalty and make two melee strikes.
If the focus is going to be on ranged weapons. Think the ranged weapons need to have an effective range to keep melee based characters at bay and do more damage on average than a strength based melee attack on a hit.
Another question, in PF2e attacks of opportunity is a class feature or feat. Is that going to be the case in SF2e or will the ranged character still get the attack of opportunity as the melee character moves to engage?
