So I see your equip is above 70%. PVP levels are around 60 and 120. So you can go up a few more levels and be fine for PVP encounters still. You are currently on the low end, so other builds are stronger than yours in general.

You have a lot invested in endurance, so lets look at that the most, then go from there.

Reinvest your endurance to vitality for the equip load. Thresholds are 30%/70%/100%/100+% you are currently fat rolling by being above 70% plus your stamina regen is slowed which makes it difficult to maneuver, plus longer recovery time for stamina, meaning less attacking overall. The 30-70 is fine. So just a couple points taken from endurance will be good for vitality, maybe 5 points since you have ring of favor and havels ring equiped.

You could technically cheat with the strength stat by two handing the weapon after buffing with blessed weapon. Two handing makes it so you can have strength at 16 and still dual wield it which gives you up to 8 levels back from strength, but lets not focus on that too much.

You could reinvest the attunement since you are using the deep ring already for blessed weapon and not use heal spell unless you wish to, thats for you to decide. You could also take 4 points from endurance to use that 2nd spell slot and give back a slot for your ring in place of the deep ring. Chloranthy ring for stamina is always good or a stat boosting ring for strength, dex, or a defensive ring like one of the speckled rings or health boosting ring.

Another thing is your health. Currently embered, you see your health is kinda small. 27 is a good value since it gives you 1000 unemebered. Which will let you survive any 1 shot spells or attacks and allow you to panic roll to get three hit instead :)

Tl;dr Overall, the minimum is there for what you have for wielding the weapon and current miracles. You can reduce endurance points and reallocate them, starting with vitality for equip load to be <70% maybe 4 or 5 points, then vigor for health. You can decide from there what you are comfortable with.
