Would it be possible to have displacement right from the begining with invisibility, (even better if it kicked in when you first attacked something during invisibility part of it)?

Asking this because now you have to wait through invisibility (because attacks wont break it) to get the displacement, which is the more useful part of the ability. The longish cooldown (4min) and the more ranks you have the longer you have to wait to get the displacement part to activate makes it feel a bit too useless ability the way it is now.

Thanks
