Yes, when you put the "read the 25y that's listed" in a vacuum, sure, it would seem simple enough. But you need to consider the other factors. Players may be new and inexperienced to the job and have to juggle all the new information while solidifying their rotation. Plus the fact that all attacks using mana have been melee, with this one exception. Plus Reprise's normal version being a melee attack. Plus how it is possible for people to outright miss the range and radius description.What's not intuitive about 25y range being explicitly listed in the tooltip like with every other ranged skill in game?
All in all, your argument of "it shouldn't be unintuitive" doesn't change the fact that it indeed has often been unintuitive.
