It's worth noting that the Magical Ranged DPS role is not called 'Caster'. It's called Magical Ranged DPS. Casts can be found on pretty much all other roles. All of the arguments against occasional casts or walking casts on Physical Ranged DPS just boil down to personal preference.

Discussing balance around 'difficulty' is subjective. There are different things that each role values in terms of 'challenge.' I think Snow makes a good point, in that Physical Ranged doesn't really have an identity currently. It's not really a 'support role', because even the likes of PCT has equivalent utility. It's not a 'damage role' either, 1% buff aside.

I can appreciate that any change to design direction is going to be met with resistance and naysayers. But there needs to be one in place for 8.0 at the latest. Otherwise, they might as well merge down Ranged into a single category and just standardize people replacing the Physical Ranged slot with a Magical Ranged.
