I heal as holy. Last week for example when a tank was starting a pull, I could cast POM and immediately cast Bubble directly after. Having 24% haste gave me the ability to basically jump from one instant cast to the next as long as it wasn't on cooldown. I had other computer issues so did a reformat and reloaded wow. Everything is working fine except one issue. When I try the same thing mentioned above I get the error msg "spell is not ready yet". Aside from global cooldown there should be nothing stopping the cast of one instant cast directly after a previous cast of any type. I find myself having to wait about 1 second between casts of any kind, instant or with a cast time. The only exception is I can spam the same cast back to back all day long (ie, flash heal) without having to wait between casts. Can anyone point me in the right direction? This is getting very frustrating across the board. Especially in healing intensive fights where I am constantly spamming heals of all types for the duration of the fight. Having to slow my reaction time and sometimes attempting to cast the same spell twice every time is getting very annoying and is gimping my healing performance. Thank you much.
