Really, the best class thing is trivial, as a player will only every fully utilize a class based upon their preferred playstyle. That's even correct lore wise, as Echo tries being a Hunter in the absence of Zeno, and she gets told her strengths sit more in a support role, rather than a melee role. So by extension, players will have their strengths and weaknesses, and should focus on honing those strengths to decide their class, and become the best at them. Teams made up of multiple classes, all with expertise in their respective fields, typically will have better team cohesion, and survivability.
