Last I checked all the hoplite weapons have 2 or more attack directions if you put your shield on your back.
Then they are no longer a hoplite. So invalid arguement.
Crpg definition of hoplite: one who wields polearm and shield as weapon configuration.
Once the shields on their back they are no longer wielding it.
You are also requireing them to master two fighting styles compared to 2h one fighting style. That is an unjust request.
I'm going to guess your rebuttal to that is that some 2h can be used with a shield. But, it is weak as well. I agree we should buff that aspect of the game as well. And give half handing an overhead swing.
