decide if a class/weapon balanced or OP.
Every class has a part on the battlefield.
Main duties to class (In my personal opinion of course.)
Shielder=Shield Wall , protecting infantry , stalling enemy , attacking archer squads.
Polearms=Anti-Cav , Anti-Shield,Poke-stunning enemies to create opportunuties to your teammates.
Archers=Harassing enemy , Killing enemy from range , delaying round by running away
2 Handers=Killing enemy infantry.
Cavalary=Harassing enemy , flanking , killing AFKers,Killing idiots who cant block down or who can't understand a horse approaching.
Of course cav and 2handers will top the scoreboards but without shielders archers and polearm guys, they'll fail that's simple.
