I'm kind of wondering the same thing to be honest. I've read on here more than a few times that Spear screws with rotations, but I can't really figure out why or how, probably because I don't DPS much. Sure, I can see how it may be less useful than the other cards due to the way it works, but how does its effect negatively impact a rotation? On my NIN, for example, I know my opener/rotation like the back of my hand and tend to focus on other things during that time. If I get a Spear, it...often does nothing for me; it shortens CDs sure, but outside of raiding, I just autopilot my opener, and everything after that is a priority system. I just don't see how having some shorter CDs would throw off a rotation.
