These fucking faggots need to get raped with barbed wire. So far this was the only boss that gave me genuine trouble.

The trick is to focus mainly on the big guy. Sprint in when the opportunity arises and pummel him as much as you can before sprinting out, keeping an eye on the flying guy so he doesn't surprise you. Ideally you'll get them positioned relatively close to each other so you don't get boxed in and so that you can potentially hit both of them at the same time. What's fucking bullshit is sometimes it's impossible to jump over the big guy when the flying one is on top of him, forcing you to parry the big guy's attacks. And I haven't really been forced to learn how to parry yet, so I kinda brute forced a win. Perhaps I should start thinking about parrying more often, especially in 2v1 situations.
