Priest Shadow form bug

I am a shadow priest called ''Rakurleb''. I found out that spamming Shadowform ability when the global cd is on bugs the Shadowform so that you can't enter to Shadowform again. You get the error ''Spell is not ready yet'', changing the instance or relogging seems to solve this problem but this is an impractical solution when you are in the middle of a boss fight or when you are in BGs. It took me a few trys to recreate the bug. You might need to use an instant spell then immediately spam the Shadowform. Some other priests also had the same problem

Thanks for the report. I actually knew about this bug but didn't know how it was produced. Thank you for testing a few things to find out how it happens. I will be sure to tell the other shadow priests so they can try to avoid this problem while I try and fix this problem.
