I must admit that this set bonus combo is truly amazing. The execute proc is fun because it gives us more options and its even better when nothing is everything is on cd/not procced and it pops up. Although what really got my attention and is an amazing addon to warriors is the bonus rage on Colossus Smash. Thanks to this I don't have one of those random rage starve moments and that burst income of rage makes warriors feel much more fast pace than before because the amount of heroic strikes we can get out.
By far my favorite 2/4 piece combo that has ever been implemented! My hopes are they get a lot of positive feedback and maybe even get added as a passive!
Keep up the great work!
