I have the two and they are the most wortless companions I ever saw in a game
They dont do damage, dont tank monsters when you need it, they ■■■■ up the quest sometimes (Like “Kill x monsters inside this tiny circle” and they keep pushing the agro to them and leaving the circle), their stamina is worthless, they take a LONG time to attack, so, if the monster walk 2 feets your companion gonna miss their weak attack
They are useful only to increase the Team Level for the bonus EXP
People say they help your low level characters, but no, they take too long to do damage and like I said, the damage isnt high, you can do the same damage with 2 hits
Buy a Token in the market or any other thing, dont buy a companion, its worthless
