Class Rock, Paper, Scissors...
It really isn’t quite as simple as that. For example, a Tempest could be a standard bunker, but then maybe the meta could shift and it turns into a dps role. Or depending on how your Guardian is built, it could be strong vs some professions, or weak vs others, etc…
It is true that a “soft, hard-counter” exists between different builds, but knowing how to rotate and pick your fights is -part- of the key to the game.
It’s to simplistic because our PvP modes are team based. So bringing X to beat up Y might work in that equation, but if A B and C are there, it’s likely X will not be a viable choice, and therefor it’s better to take Z since he can provide something while not having to worry so much about A B and C..
Which is pretty much the way things are now, and why there’s zero diversity.
