Bliss and Enzo, when they first debuted on TV, were miles ahead of where Eva is right now on TV.
Bliss was...really, really bad. Because, like Eva, she had almost no training and was relying entirely on her gymnastics background to carry her through. Even now, while dramatically improved at looks, promos, attitude, swagger, and character, she's still just passable in the ring. And she had a year of daily training at the Performance Center before she was in the ring on TV. Eva has a few months of training with Spanky.
They didn't train her or she had no interest/put the work in? I guess it don't matter if she cares now.
Not like they gave a shit about divas matches 2 years ago. But it's not coming along naturally.
I think they just didn't see a reason to train her. She and JoJo both were hired to be ringers for Total Divas, not wrestlers. All the wrestling stuff was just there for footage for Total Divas and it didn't matter if it was good or bad. In fact, being bad was part of the story on the show, as the other girls were "jealous" and mad because Eva was so bad. Then things went a different direction, and now Eva is putting in the work to be an actual wrestler instead of reality TV character.
Wrestling fans bought into Total Divas-verse so hard. It's amazing. Those writers made people believe that Nattie had never heard of doggy style, Tamina gets into fights with tiny Asian men throwing spinning round house kicks at bars, Summer Rae went to Nattie's house to slap her, Nattie left Summer stranded on the road in the middle of nowhere, and other completely ridiculous story points that people now apply to the real people and their wrestling characters.
