No the usability is the point. Jump Sequence needs Giant Leap to have went off in order to be used. Casting Giant leap mid fight is always almost gonna end up with you being grabbed out of it. Wolf's Frenzy's i-frame is pretty much nonexistent, after the nerf or fix. Flash Step is usable. Silent step too, but with enormous gaps. This post is about i-frame spamming being op and neither of those classes can do that.
