In my opinion, this decision was a step in the right direction and a solid compromise between different viewpoints.
I would have personally left the silver Stick 'Em Up and Truculence abilities available. I have a small concern that this change might actually lead to even more passive defending than ban on all X-Factor abilities would. My reasoning: One-timers will once again become very high-probability scoring chances, as will close-range shots with the Close Quarters trait. At the same time, taking away the most effective defensive tools for pressuring puck carrier may leave the best option as simply falling back into a defensive structure, trying to intercept passes to one-timers, and keeping opponents away from the net to prevent Close Quarters goals.
I hope my concerns turn out to be wrong and that other defensive abilities provide alternative ways to pressure puck carrier, or that the "pressure system" ensures pressuring the puck carrier remains viable.
The good thing is that now there are only two ability slots available, so if you want to pick a defensive ability, you can’t take both 1T and CQ boosts.
I’m happy with this decision! 👍
