Question abt spirit's skill: i hd bought a cast helm recently..although my spirit cool down time changed from 9sec to 6sec when i equipped cast helm but i still need to wait till 9sec if not it will show Skill Not Ready..is this a bug or wat?

it's a bug

Yes, even a year later, it's still a bug, and what's worse is if they even did something like fix it on spirits to do regular cool time instead of cast up (even if castup is equipped) would be better than having to wait 12 seconds instead of 9 because you had to wait for the animation 2x (once for casting and once for the "skill not ready".)

Either that or use the rule that elementals are an extension of an elementalist and should get the cooldown based on the summoners equipment, and just fix what would be then considered a bug.
