Is Harm Touch not supposed to let you know it is on cooldown?

[Zenshu]

Its been over 10 years since I played EQ live, so I can't remember whether Harm touch is supposed to indicate through the hotbar button that it is on cooldown or not, it would make sense that it should indicate in someway that the ability is on cooldown, but that is not how it is currently working, the button remains "drepressed" for about 6 seconds and then refreshes while Harm touch is on cooldown for 70+ minutes. the only other post I found about this was from years ago and the only response was someone telling him to use a kitchen timer and the thread was locked....is this how Harm touch is supposed to work? with no way other than buying a kitchen timer to know if your ability is usable or not?
