I was really excited about the new talent "Primal Gore" that is going to allow Lacerate and Rip the chance to crit. Then I learned it has a pre-requisite of "Rend and Tear". That ended the thrill for me.
From what I can tell Primal Gore is being designed as a PvE only DPS boost. Now the question you will have in response to this is "Why the heck do you think that?" The answer is fairly simple: Shred.
As it currently stands, in order to take Rend and Tear, you have to sacrifice either utility or survivability. On top of that, if you do that 5 points into Rend and Tear you might as well sink an extra 2 into Shred (-18 Energy cost) so you can actually use that ability. So we're essentially talking a whopping 8 talent points for Lacerate and Rip crits in PvP. 8! Here's a summary of what you have to lose in order to get that one talent:
1) Master Shapeshifter (2 Points): -4% Crit in Cat form and -4% Damage in Bear. I like it for the crit and extra combo point generation - allows for easier Savage Roar upkeep (which is infinitely more important than any other finisher).
2) Natural Shapeshifting (3 Points): +30% Shift Cost. This might not be a such a big deal - except with this and Primal Tenacity you will be down to a 224 mana cost Cat or Bear form. 224. That's it. I don't know about you, but I like having mana available to Cyclone, Roots, Heal, etc.
3) Thick Hide (3 Points): -10% Armor. This is probably the first one I would lose if I had a choice - although I would really rather not at all. I like the survivability.
4) Natural Instincts (2 Points): -20% Healing in Cat, -70% Agi as Healing Power. No. This is such a huge survivability talent I would never give it up under any circumstances.
So I'm forced to pick 8 of those 10 points and throw them away for a talent I would never use anyway if I had Rend and Tear (if you have R&T you better be using FB and not Rip)? You have got to be kidding me.
Make the pre-requisite Imp. Mangle like it should be.
