3/3 cobra strikes is wasted.
Pets get a lot of crit from themselves and talents... pets just cant use up the cobra charges, ofcourse, gear is a factor here too, the better your gear the worse cobra strikes gets.
Actually I don't see cobra strikes as this bad. It is not a great talent, but spending points on it is not a total waste after all.
Lets take another approach to see why.
The normal crit rate of a BM pet is:
5% standard crit rate
+10% from BM talents
+ 9% from pet talents
+ x% from raid buffs and mob debuffs
So we are looking at a crit rate of 24% + pet buffs and mob debuffs. Lets assume a raid buffed pet currently gets to 30-35% crit rate (leader of the pack, mob debuffs plus stat buffs).
Since the crit rate of your pet is not bound to the hunter's gear and cobra strikes only procs from special attacks (which are bound to the GCD), the pet should be able to eat up the charges before it procs again.
But how much damage does cobra strikes give us?
I'll try to answer with data from a BT run we did yesterday.
Over all boss fights (I ignore trash fights as those mobs never are fully debuffed and vary in their level) my pet had a crite rate of 35% with normal attacks.
However special attacks (claw and rake) had a crit rate of 50% and 49%.
Here is the WWS from yesterday so that you can see the numbers I use as a reference:
BT clear Since only cobra strikes increases the critical strike chance of my pet specials I can safely assume that cobra strikes (which I have specced 2/3) increased my pets crit rate on special attacks from ~35% to ~50%.
By looking at the avg damage values of those abilities a critical claw hit gives an extra 349damage and a critical rake hit gives an extra 423damage.
Lets calculate the overall damage gain:
claw: 595 hits (of which 300 where crits). With a 35% crit rate my pet would have crit 595*0.35 = 208 times with claw. So cobra strikes gave my pet 92 critical strikes with claw which gave my pet 92 * 349 = 32k damage.
rake: 100 hits (of which 49 where crits). With a 35% crit rate 35 my pet would have crit 35 times with rake. Thus cobra strikes gave my pet 14 critical strikes with rake or 14 * 423 = 5.9k damage.
So in total cobra strikes gave my pet 38k extra damage over all boss fights. My pet did ~1m damage against those bosses, thus cobra strikes is about 4% of my pet's dps.
Me and my pet did about 3m damage in total, thus cobra strikes was responsible for a about 1.3% of my total dps.
So as a answer to how good cobra strikes is, I can say that cobra strikes seems to yield ~0.65% damage per talent point.
If a talent gives you more in terms of total dps, it is better than cobra strikes, if it yields less, it is worse than cobra strikes :)
Anyone seeing flaws in my assumptions and calculations?
