Yes it is weak damage but its a cone in front of the pet so its aoe, would oyu rather do a claw for 50 damage or 111 damage to 10 targets (unlikely yes but still).
Nothing beats wind serpents - they start with +7 DPS, and then their lightening breath is instant and isn't channeled, its 20yd range so it adds pure DPS. Very good pet. It even can have more DPS than a cat.
I love mine ... would never get rid of it for anything else.
Note: There are plenty caster bugged ones so be sure to check before taming. ;-)
my lvl 8 one that i started with was 18 damage over 2 secs
lvl 12 now, does 30 over 2 secs now...so it added 3 each ding....i'd assume the same for the rank 2
I'd say this would be good for both but in instances and raids i'd say leave it off auto cast so it wont pull hate from the tank/s but i have a friend who uses one for pvp, one word pwnage he is sick when chasing a grp with the flag cause he hits fire breath and whole grp takes the damage.
Coulda sworn it hit for much more then around 100 cause they all lost a nice chunk of hp from what i saw.
anyways IMO the dragonhawk is great for pvp and pve but his skill not gonna get as much use in dungeons where you got to cc
