By CX I assume you mean policy and no, it's really effective. I did it for 4 years and it was rare if my partner and I didn't place and one of us nearly always won a speaker award.

Nuke War impacts? yeah, I'm running Compassion Fatigue K. On AFF you better believe I'm running a kritikal case with 'dismantling patriarchy through discussion' as my primary voting issue against the ridiculous Mead cards the neg was going to bring out.

All I'm saying is that it certainly can be effective as this is what I did and found great success both locally and in the national circuit
