Primalist or Mage?

So, im having some doubts which to choose…

i played some Mage Sorcerer about 3 months ago, but then the Runemaster or whatever is called is pretty much a Sorcerer on steroids, deffinitely looks, strong, has lots of versatility, but im afraid that it happens kind of the same as the Guild Wars 2 elementalist where you have to learn 9232 skills and its more of a memory game …

The Primalist im interested in either the Beastmaster or the Druid, but i have few concerns.

The druid while i like the bear, i want more the “forest thingy” the Groot wannabe form, is it good ? does it do nice damage ? do i control nature ?

The beastmaster my concerns are that the pets are not really configurable or amoldable. And that they cant be customized
