All pets now receive 40% of their master's resilience and 100% of their master's spell penetration. In addition, if a player is at their appropriate spell hit chance or hit chance maximum, their pet will be at the maximum for spell hit chance, hit chance, and expertise. If they are below the maximum, their pet will be proportionately below those maximums.
Resilience will help go a long way toward reducing or eliminating crits on pets. And PvP gear is usually a decent way for mail wearers to stack up on stamina.
The change on expertise is interesting. It is a touch difficult to parse because it's a run-on sentence. But what I see is that if I'm hit-capped, then my pet will be hit capped (and spell-hit-capped) and expertise-capped. This seems to mean BM hunters wont have to take Animal Handler. So from a Hunter Pet Tank stand-point, these are two talents we might want to use elsewhere. Of course PvP gear isn't the most +hit intensive gear around, but Focused Aim would be a better choice now. Again, I'm talking about Pet Tanks here.
Catlike Reflexes now also reduces the cooldown of your Kill Command ability by 10/20/30 seconds.
This is a buff to BM dps. It's especially a buff to hunter pet tankers since we already take Catlike Reflexes for the 9% dodge. Now we'll get Kill Command every 30 seconds instead of every minute. That's very nice for threat generation. DPSers will probably take the two points from Spirit Bond and put it in this now.
Beacon of Light: The healing amount on the Beacon of Light target is now based on the total healing done (including over-healing) instead of the effective healing done. Radius increased to 60 yards. Multiple Paladins can now have this active on the same target. Buff indicating a player is within range of the Beacon target is no longer displayed.
The above Holy Pally ability is usually used to heal and supplemental heal a tank. The first look at it is "Wow! They will be able to Beacon the same person." Second look is, "Wow! Overhealing will count." My look is "Wow! It's based on Healing Done." My only question is, "Can this be used on a pet?" If it can, then this may be interesting. Hunter pet tanks had been taking Spirit Bond and the pet talent, Blood of the Rhino for the healing increases. Well those are a +10% and +40% to "all healing effects". So the hunter pet OTs. The MT gets heals off the hunter pet equalling 150% of those heals?
Mmm. I suspect this wont work for some reason. However, if it does I don't see them nerfing it. In order to use it beneficially, you really do need a BM tank pet. In order to not waste a perfectly good beacon, the pet should be taking damage. Otherwise you'd be better off using a heal on someone else. I don't see people throwing heals on dps Tenacity pets just to get big beacon numbers. 1) You'd have to use a core hound. 2) Assuming the pet is at full health, the pally would only achieve 150% healing, whereas if they use it on someone who could take the full heal, they'd get 200% of the healing effect.
