stats, only 26% haste for better SB uptime you ovbiously want more without recpruc.
at the end of my 13 minute fight i had about 60% shield block uptime without repruc.
the zinger ofcourse with anger management and only 60% SB uptime is this 30% uptime on demo shout in a 13 minute fight.
in a mythic + which does not require you to have full SB uptime because you have reset time in between pulls, heavy repruc is just not as juicy as it was. and if for some reason you NEED shield block uptime, nelthing on CD will give you that reset time for your shield block charges as well.
