Alot of misinformation here,
1st- glyph of the hawk has more usage in a raid environement than kill shot simply for the fact that you will NEVER do 3 kill shot on a boss other than sometimes on LoD if harvest soul's rng is bad, hawk has way more use than kill shot, especially on the previous 11 bosses.
2nd- its not about arp outweighting agility, arp always outweights agility, its a matter of how much you have to start off, the 700-800 passive arp treshold is simply for the fact that steady shot will outweight arcane due to that exact amount of armor pen, not because that at this point ''arp outweights agility'' , it always did.
3- no other pet than wolf is viable in PvE content, furious howl, call of the wild and rabid simply makes it the best, the rests are ****ing useless, if youre not a BM hunter, use a wolf period, no point in even considering a wasp or a raptor. you already provide healing reduction from aimed shot.
