The fight is easier when you reduce environmental friction and keep enough room to react to movement changes.
Create enough usable space
Do not let nearby terrain become an extra obstacle during the fight.
Prioritize controlled movement
Reliable movement can improve both survival and damage uptime.
Choose a weapon that works while moving
A weapon style that lets you attack without standing still can make learning easier.
Adjust one weak point after each attempt
Change the system that is actually failing instead of replacing the entire loadout.
