Fighters - block claw swipes and avoid getting grabbed, spam antler toss on heart since it has a tremendous stagger bonus, when it falls, spam dragon's maw.

Striders - dodge claw swipes and grabs with roll, spam skull/brain splitter on heart until it falls, grab it and kiss it to death

Warriors - exodus slash in response to any attack, jump attack on heart until it falls, jump attacks on heart until it dies

Assassins - if you're using a sword, short answer is switch to daggers, long answer is see fighter for defensive strategy and when it falls, attach and use dire/deadly gouge. If using daggers, masterful kill or dodge against every attack, attach and use hundred/thousand kisses until it dies

From personal experience, for the fastest hassle-free dragonkin kills, use the strider setup or a magick archer setup with immolation. Dire versions of all dragons can be killed solo in less than 30 seconds.
