Horo had six seasons in the NRL with Parramatta and Manly before joining the Dragons at the end of 2015.
“I’m still kind of building my way in the Super League,” Horo told Love Rugby League.
“I just think the consistency for an 80 minute performance is the difference at the moment.
“You look at the three games and all three Super League teams competed well for 40 to 60 minutes and then kind of just dropped away. And that’s when the points came in the last 20 minutes.
“So it’s just being able to play that 80 minutes. I know that’s thing in our team, in the first few games we’ve played really well in patches.
“But that’s the main thing, just being able to play for the full 80 minutes, which the NRL teams have been able to.
“It would probably help [to have it] more mid-year, especially with the turnover that happens these days with teams, that’s a big factor as well.
Horo would like to see the World Club Series expanded and held on neutral soil.
“Definitely, I’ve heard talk of them expanding it,” he said.
“I think it would be great taking it to a mutual zone and expanding it.
“I think it’s a great idea, I’m sure even if it wasn’t in England all the people in Europe would be pretty interested in the game no matter where it is if the two competitions are going head to head.
“I’m all for it and I hope it stays around.”
