This patch is now live. Here's what you have to look forward to upon logging in.
Old Words of War - 20 Endurance + 16 AP + 250 AP on use
New Words of War - 20 Endurance + 60 AP/Vengeance on use
Old P7 Synergy Crystal - 500 HP + 200 AP
New P7 Synergy Crystal - 500 HP + 75 AP/Vengeance
If you haven't heard of Vengeance, its a new stat. Essentially, its Attack Power that only works in PvP.
If you're like me and did the grind in Codex and to P8 so you could have the best gear possible for PvE, you just lost 141 AP in a single, shining moment. Really, its more than that, because you won't have the use function of Words of War anymore. The trinket is now garbage for PvE and basically anything else is better.
The Cold Heart (final boss of DH) remains best in slot, but now there is nothing else even close. Start running DH and hope your luck is running hot.
Top 5 Trinkets, ranked:
Its hard to say if the P8 gear will remain BiS until HK. At the very least, you will be more inclined to break the set earlier in HK, so having the Raid 1 pieces to use when that happens will be important.
I parsed 2049 DPS on Murdantix this week, using Dundancer. We'll see next week how much these nerfs have hurt.
