The state of WK polearm and shield

The current state of Polearm and Shield WK is just sad. I'm giving up on playing until it gets some heavy buffing. It's easily countered by:

Shadowstrix: Their dash skill goes trough your block and stuns you, leaving you open for backstab damage that pretty much does half of your health in damage.

Mercenary: Their superarmor when confronted with our shield bash (dash) leaves the WK stunned, so in almost every trade we lose.

Sorcerer: The true damage of his skills leaves you with 30% health by the time you get close enough to hit them.

Blackarrow: The same as the sorcerer, the true damage negates all my tankness, by the time i get close i am already almost dead.

Seer: The only one i dont have to much problem with, except when they get that constant super armor, the only thing i can do is dash alway until it ends.

Conclusion: It is supposed to be a tank class, but it cant diminish any damage. I think they need to buff up the block, give some superarmor or something. Those are my opinions, i am just a casual player, but thats some things i see that are wrong with the class, feel free to criticise my view, as long as the game grows and get better i am happy. English is my second language.
