For personal use the dragon, specifically magic.
As a clan, a seedling, specifically magic.
Yes indeed..
Even for own dps (mainly auto dmg) is seedling better.
I strongly advice you to get seedling as its most value for overall..
Ive got dragon (magic), phoenix (armor, posion resist, evades) and also magic seedling.
I use the magic seedling 99% of the time.. and phoenix for pvp..
Dragon is garbage (for me and my playstyle) only sitting in. My backpack...
Wish they implement some kind of exclusive shop where you can sell back your exclusive pets and now mounts (chest material mounts, hellsteed the first introduced) more to come for sure..
Fake news!
The dragon's skill does up to 2000+ damage at max tier and maxed out ability with a 15 second cool-down time.
It also is unavoidable - therefore guaranteed damage.
In 15 secs you could possibly auto attack the boss 13,63 times, considering you're haste lixed:
2000 damage divided by 13,63 is 146 extra auto damage, compared to the seed's 100 extra auto damage.
So not only is the dragon better for dps overall, but auto attacks can miss while the skill is unavoidable, so it's even better.
That + the 1000 extra points in crit ability.
There's no doubt that the dragon is the best pet for one's personal DPS.
