2 - https://wowroad.info/?spell=66 does not puts you out of combat ( witch cause another issues for example , not being able to win some extra time with "blink + invisibility" against the oozes at professor or ice tombs at sindragosa with pre-casting mana shield + frost ward on the right time... etc etc )
3 - it should get you out of combat at least for 0.1 sec ... so issues that i mention above won't even bother us :)
4 - last week into the 100x wotlk realm
5 - last week but it has been that way for years i think ( because i am new into the server )
6 - https://wowroad.info/?spell=66
7 - it is permanent ( but if any from the testers want's to "play" with it round he can try some tricks with mage at professor / oozes trying to make them interrupt their cast and re-cast and also at sindragosa the known tricks with pre-casting mana shield + frost ward on the right time 4 sec before the ice tomb fall on your head so you can actually skip it with invisibility spell ... etc etc ) experienced players will understand me
8 - if someone need any video that proves the issue let me know here as comment and I'll do the effort to research and cut some unlisted stream of mine.
9 - I hope to be understood correctly ( i am not some mad nerd i just used to play with amazing group of players in the past and i know which eventual reports can cause negative effect as general to the server in terms of "population lost" or similar , so please understand me that i am reporting ONLY "bugs"/ wrong behaviors which fixes, will make the game-play smoother and more enjoyable and NEVER gonna even try to report anything even if its better in terms of "blizzlike" , which will cause suffering from the players side.
