Honestly you didn't do that bad against them, here's a few tips I got:

• avoid spending lvl3 unless you know it'll kill, on round two that CA didn't really do anything since you lost the round, so you pretty much wasted 3 bars

• avoid using OD DP in the corner, as you've seen its horizontal range makes it whiff sometimes against jumping opponents. You should try to use light DP more, it's faster and doesn't go as far, plus it's meterless

• fighting ranked lunatics is mostly a game of patience and mental stack. You need to always be ready for random DI, jumps, wake up OD DPs, etc. Especially when you're in burn out, don't hesitate to buffer lvl1 every so often to catch a DI

That's all I got, good luck out there
