Guild Wars 2

I’ve recently rolled a warrior for some spvp fun (since no one seems to like them) and I needed some advice

I’ve been playing a healing shout hammer mace/mace warrior in spvp for the last week and I have found it very very fun to play and actually amazing In a team fight when combined with a zerker or high damage class. My question is: are there runes to increase either knockdown or stun duration? Right now I’m running 2 sigil of battle and 1 bloodlust along with soldiers runes for the condi clear on shout. Does the sigil of paralyzation effect the mace stuns? Or the hammer knock downs?

Thanks for helping!
