Not trolling. I've only played Catwoman since EVO and I will be using her at VXG.
Nothing has changed my mind about how good Killer Frost is. It's not about that. I still think she is a better character than Catwoman. However Selina is my favorite character. I never had a passion for KF, I was playing her because she was so good. Before UFGT I was playing both Killer Frost and Catwoman. Shortly before UFGT I decided to focus on Killer Frost because I was doing extremely well in casuals. I thought I could show how good she was and do well in tournaments. I've done ok but nothing spectacular. Now that she's normalized and I'm not placing top anyway I see no reason to continue to main KF. I'm going to play that character I love, which I should have done from the beginning. After UFGT it was like ok it's too close to CEO to switch. Then it was too close to EVO. I had a lot of MU exp with KF and was doing well in casuals at tournaments so it didn't feel time to switch. I was always emo though. I was torn between playing my favorite and playing my best character. But now I'm just going to play Catwoman. I'm probably not ready for VXG, since I just got back into playing her and am behind on tech and matchup knowledge, but since playing her since EVO with the GGA guys I've been re-motivated and had fun.
So, yeah, I'm not dropping KF because of her nerfs or anything. She's good and I think guys like Rog and Khao will rep her well. I might still use KF for a couple MU too. Since I've already ruined being a 100% character loyalist like I was in MK I may still use KF. At least for a while. I'm thinking for Green Lantern and Aquaman.
