I don’t think runes should be considered part of the moveset because you can’t always use them, and you can change them. Furthermore, using them only moves you away from the target, not into the position you’re going in, like the shortbow’s running attack.
Cool, It should probably be a different rune that costs 25 focus.
The twined Recurve bow’s running attack would make more sense on double daggers and fists. Obviously, you can make it work. I agree that it can be strong, but I find it unnatural. Maybe it would make sense as a rune that consumes stamina, but in my opinion, the bows’s running attacks should let you go in the direction you want to go.
In my opinion it should be a different type of charged attack, more similar to that melee weapons, obviously shoots a stronger and faster arrow, but it is not a modular charging like that of other bows that have a charged attack but something more similar to the fast charged attack that have weapons like the Scimitar.
Anyway, I have already expressed all my opinions on bows in this topic: NEW BOWS Movesets and Runes can be Improved
If we want to continue talking about bows we should do it there xD.
