Jump with bows, Shield durability and free shield points imo.
1: jump with bows - I found with small bows and long bows jumping with them drawn even when standing still gives you a massive advantage, because any approaching infantry, if you jump and shoot you shoot right over the shield and headshot.
2: Shield durability - shields break too often imo, and if your playing a shielder it sucks if your shield dies after about 3 hits from a 2h axe
3: free shield points - just means that 2h and polearms can carry a shield and not just be screwed if the other team has like 5 archers. Still difficult for them but at least they have a fighting chance then.
