Lol. That’s pretty OP when levelling, you could literally form a party, set your pet to growl for the 10 minute duration, have someone continously lure mobs into it while you / other party members kill off whatever is frozen in fear ^^
Pretty damn OP for levelling alright.
Not really 
becuz party of 5 can kill mobs pretty efficiently anyway it would be a waste of time running back and forth. I actually didn’t got myself into situation where I would need this skill and pet is more useful when its roaming around and doing some actual damage. PvP is entirely different tho and Growling is stupidly strong there.
Actually you might help me out. What does rush dog / hunter’s pet damage scale off of? Just your level or some stats have an effect?
Pet has it’s own level and stats - STR CON etc so skill damage always scales with pet’s physical attack. It is probably the reason why Hunter’s skills don’t have enhancing attributes at all - because you can upgrade your pet instead.
what does grown in pvp ?
Nothing, it was disabled almost instantly after it was added.
and what was ? for curiosity, too bad, so hunter c3 worth less now ?
