Won what fights dawg?
He has lost EVERY SINGLE FIGHT where the person he is fighting is equal or stronger to him.
Morock was fighting mfs STRONGER THAN DURZA and lost because of bad writing.
What reason did Durza have to lose? Durza got fucking molested by Theos, so much so he was running from the guy for 800 years.
Then of course he hid from Cursebeard, had to revive big dick zeus to save him, and had to rely on emotional torment to win any fights
Oh and lets not forget, when he got the Absorption Curse… he still got molested by a literal low level bandit using light magic 
Atleast Frauden had the ability to combo a semi-skilled user who had a curse for much longer than him, whilst he only had his curse for like 1 month dawg 
Stand disgraced durza, your biggest feat is struggling to beat a light magic lvl 1 bandit
