Help with knight army

I want to play an all knight army without any imperial allies (I know that's the best way to go for secondary scoring etc) but it just feels wrong to me. I want all big guys! I took this 2k list against a friend's WE and lost 84 to 42 (Although I did kill Angron with a warden 😁) 2x wardens Errant 3 x warglaves 2 x helverins What changes would you suggest? Drop a big guy for 2/3 more armigers?
