What Went Wrong?

[Tarot Cards]

My starter gladiator, a 2H War, was doing great all the way through the Gladiator tier, getting ranked 2nd there. The moment I hit Veteran tier, I started losing, badly. And I'm still losing more than winning as I go into Elite tier. I've played around with different strats, and managed to come up with a set of actions that helps me lose less than normal, but all the same, I've gone from a 70% win-loss ratio to a much worse ratio. Right now, she's wearing all green medium armor (any heavy armor puts her in the orange zone, which absolutely murders me when trying to land enough attacks or avoid running out of stamina) and wielding a green 2h mace (no good blue 2h have popped up in blacksmith recently). All skill points are in 2H weapon skill, which just hit 7. Her stats are

Strength
65
Intellect
56
Agility
64
Stamina
64
Size
56
Presence
65
Chi
58

And my fight strategy is this:

Priority 1: Standby Activity: 10 Bash Head Defend Torso Bloodlust 10
Priority 2: I Am Moderately Injured Activity: 10 Parry-Bash Head Defend Torso Bloodlust 1
Priority 3: I Am Moderately Tired: 4 Parry-Bash Head Defend Torso Bloodlust 1

What can I do to improve my glad?
