Before nudge, I used to enjoy fighting Rusty, Maduin, and the top swashbucklers. I could win, but it required concentration and perfect execution. Now I'm just a bug on their windshield, with no prayer of winning the fight (save resorting to nudge myself, but that's not my thing).
Any mechanic that can change a 50/50 fight into a 1/99 fight by pressing one button is a broken mechanic.
