Polearms OP? LOL you're funny So I'm in the wrong for going a pure build? nice real nice. Either way I don't care because I really hope this wont be added and will just be ignored like all the other cav nerf threads out there.
You aren't a pure build. You're lancer cav/infantry hybrid. You get to spawn on a horse with the best lance and the best polearm of your choice every round with a barely gimped statwise build with two lives and exceptionally high impact on winning a round due to the nature of cavalry.
Most comparable hybrids to versatility are the ranged/melee classes. This is why the 1 slot regular crossbow is OP as well, you can bring top-tier infantry weapons for hardly any skill points or drawback and the crossbow has excellent stats.
2 slot ranged weapons + ammo slot (3 slots) with 1 slot melee weapon makes sense, but is underpowered in comparison. Especially with the PD and WM requirement of archery, so they suffer from slots and skill points. The lances offer WAY more killing power for 2 slots then these ranged classes get with 3 slots at the cost of riding skill only.
