The Wolfhounds were handed the toughest of groups, drawn against Australia, England and Fiji, while the other home nations – Wales and Scotland – have done battle in the highly competitive Groups C and D.
Aston said: “The group was always going to be tough but we spoke about that, and we wanted to come out of it loud and proud.
“It puts into perspective where we are as a developing nation, and it will serve us well in the future.
“Yes we would have preferred to have been in an easier group, but we’re not going to moan about it.
“That said, I don’t think any of the home nations get the right sort of support.
“We went into camp two weeks ago, and we’ve had maybe 10 or 12 sessions together which makes it very tough.
“If there was more finance, we could have gone away and spent more quality time with each other, but instead it’s kind of just been thrown together.”
Finn said: “We’ll take encouragement from the second half display. England‘s 20 minute purple patch in the first half killed the game off, but our 17 blokes went out and had a good dig.
“They put plenty of pride in the shirt, and that’s all we’ve asked for from minute one.
“If we do that again next week, then we’ll walk away from the tournament proud of ourselves.”
