One thing I noticed immediately after the 5-slot role skill restriction was lifted was I felt like I went backwards a bit on the learning curve. Granted, I am also still leveling. So in addition to the role skills I also have my new SB abilities I am working into my gameplay as well. Result: missed skills, misused skills, and just a general trip to derp city. It's better now, but there was a definitive adjustment period despite that I already had all skills set to my crossbars anyway.

That being said, I will also mention that there are times where I make adjustments to my crossbars, which can produce the same derps. I do try to plunge into lots of solo content to get things into muscle memory, and try to bring FC mates along for such situations.

The more a skill is used, the better we get at using it. So abilities like Rescue with really long cooldowns and limited situations to use it has many healers misusing it, mistiming it, or not using it at all. For more common skills like our gcds and ogcds on a short timer, I tend to notice when they are misused rather than not used, and this is largely due to the sound effect, which means I need to be familiar with it. I don't notice any derps from DPS players right now unless they take unnecessary damage. That's it. When/if I start playing these jobs, I will notice a lot more when I hear or see their skills firing off when they shouldn't.

Other than that, I am too dialed in on what I am doing to pay attention to what my team is NOT doing unless what they are not doing is clearly making things go south. I'm not a babysitter, and I am relying on the playerbase to know their jobs so I can concentrate on mine.
