So with PP you need to stack proj speed now, I assume. Not sure how much you need for say, barrage. They made it so it fires on hit, not on attack. So you're going to need attack speed and proj speed, but the closer you are to a target the closer to the proc limit you'll be.
Also does anyone actually know wtf is happening with summoning. I played hundreds of hours of spectre summoners and I have no idea what it means really. Bones of Ullr no longer +1 spec, but gems will add +1 specs based on level. Adding levels to spectres helps their accuracy/defense versus mobs but spell casting spectres already always hit and with soul eater gems they never died anyways. Not sure what we're truly getting out of +1 spec level except if some one is oddly using melee spectres.
