[suggestion] more active defence
I think that if these changes were made then you’d have to give the classes less dodges, like reducing vigor uptime, since decreasing the duration and cooldown pretty much gives them extra dodges.
If these changes were made I would never bother using a shield on a warrior again. Not that I have much reason to use it now. 1s is just really useless. For some longer channeled attacks it might not even be able to block 1 whole attack. Halving the healing from SoA is debatable. Changing Feedback like that would just be a buff for most situations.
A shorter CD is just as likely to encourage less thinking because you can use it again in a couple of seconds anyway. Especially if you also take the trait to reduce CD.
