Death Punishments
I don't think the death penalty is strict enough. I recently had a game where I owned at pvp and at one point I had 21k gold but they managed to get a portal flag and kept suiciding to lock it, eventually taking the second portal flag and continued suiciding to lock them and the grunts overwhelmed us.
It was a 2v2 so we couldn't risk leaving the base when there were 3/4 portals attacking our citadel.
I think there needs to be a gold loss on death and players can reduce the gold loss with the citadel upgrade.
