I am not happy with the change as:
1) "Invisi" does not help, lots of mobs see invisi.
2) You need to click off invisi (or attack to break invisi) to be able to re-use FM which is the huge pain when you use FM in hurry/urgent cases.
What is the feedback from people who asked for change and did they find any use of invisi past ToV I mean...
I vote for ancient version back in game.
