Katana DA slotting
I slot Parry (DA's clone in Broad Sword) with three damage, one accuracy and one defense buff. But I'm running Focused Accuracy and have set bonuses that give some nice +acc. If you leave out the defense buff, DA is only boosting you 15% to melee and lethal per application. So if you're not running a defense-heavy set, you'll probably want that little bit of extra def so you're softcapping yourself with two applications. Of course you won't be able to have two applications ALWAYS, so more defense from just one is always beneficial (for example, when absorbing an alpha). Plus, more defense will help you overcome any defense debuffs you run across (I'm looking at you and your freakin' katana, Chimera!).
Well, considering that it's already got such a ridiculously fast recharge (thank you damage formula!), more recharge isn't really all that important. It's already going to be able to be double stacked reasonably easily. All you really have to slot up is the damage (3) and the accuracy (1-2). The remaining 1-2 slots can easily be given over to defense, recharge, or endurance. It's a remarkably easy power to slot.
