I picked up a pair of skirmisher's bracers today and was happy to see 8% doublestrike on them. Then I noticed that the doublestrike was an enhancement bonus. Hmmm, does this stack with out doublestrike items which are morale bonus I thought? Nope, tried on another doublestrike item, didn't stack. I thought perhaps it was just a typo, so I tested it out with lightning mace, with is also an enhancement bonus, didn't stack.
So, it appears that all items with doublestrike on them are now an enhancement bonus. I am assume this was done because, after about 2 years of complaining, the fact that the bard some inspire recklessness doesn't stack with doublestrike items and is essentially a fort debuff for more people, is being changed. As somebody who plays many a bard I should be jumping for joy, but I'm not. That's because I realize that tempest rangers and wind stance monks also use enhancement bonuses to doublestrike, and that this change is a HUGE nerf to those classes.
So, while I would like to say thank you to the devs for making inspire recklessness stack again, I can't, because I know it comes at the expense of rangers and monks.
So I would encourage the devs to re-type these items to yet another doublestrike type. Why not just equipment bonus? Then everybody can be happy, and a benefit to one class doesn't have to come at a detriment to another class.
