Background: Same community as before -- mostly-freeform online RP in a proto-MMO.
This time, my problem concerns combat in particular. I have received quite a few accusations that my problem-character is overpowered in combat -- commenters usually point at her aggressive ("make your own opportunities and relentlessly fight to kill") combat style as at least part of the reason for this, and it has been suggested to me that this style denies other players agency over their character's behavior -- this occurs because the other side wants to do flashy, cinematic things, but cannot because my character winds up punishing them harshly for it, causing them to resort to "block, block, dodge, block, dodge, take a hit, block, block, dodge, take another hit, ...", which leads to a thoroughly one-sided and unfun fight.
Is this a fundamental issue with the design of my character and how she fights? Or are there stylistic adjustments I am not seeing here?
