Question about AoE Spell Max Range Mechanic

Hello,

I'm having issues with AoE spells like mage Blizzard, warlock Rain of Fire, or hunter Volley. When I try to use these spells, I can place the targeting circle beyond the maximum range, where it changes to a red "out of range" indicator. This is often frustrating when I want to quickly cast at max range, especially while moving.

I saw a video where it looked like the player had their mouse cursor automatically stop at the spell’s maximum range, preventing it from going beyond that limit. Does anyone know how to achieve this in 3.3.5a servers? Is there maybe a macro or addon that could help with this issue?

Thanks in advance for any help!

That's only a feature in modern clients.
