im no pro but this is what i do:
Hunters mark
Trap (You get these soon, only use it really if its a higher level than me)
Pet Attack
Concussion Shot (Just as pet gets to enemy incase it stuns)
Serpent Sting
Arcance Shot
Then wingclip if enemy gets close, back up and concussion shot again so they are really slow and run away a bit and start again
As for pet, im not sure myself, i have a dino thing same level as me, he doesnt have any skills though, but he can take loads of damage, i dont know wether to get a new pet now there are better beasts out there or stick with him
Wouldn't it be better to do the serpant sting towards the beginning? As it takes 20 seconds to do it's full damage maybe:
Hunters Mark
Concussion Shot
Serpent Sting
Pet Attack
Arcance Shot
