Republic of Ireland skipper Shane Duffy admitted an inability to take their chances had cost them once again.
"Both sides cancelled each other out again. It's come down to chances again and it's probably the same old story we haven't finished them off again, so it's disappointing in that way," he said.
"But I thought we played some good parts."
Asked about the impact of the Covid withdrawals and a gruelling two hours in Slovakia, Duffy added: "We had to dig together and if anyone questioned us, we showed that we've got great spirit - everyone knew that - and togetherness even though we were short on bodies.
"It was out of our hands and this is the way the world is at the minute. We feel sorry for the lads who can't be involved and play for their country, so it was a little point to go out and do it for them as well."
Wales skipper Aaron Ramsey was happy enough to emerge with a point.
He said: "We have seven points now and we're quite happy with the way things have gone so far in the group. It was a difficult game today, we found it hard at times but it's always a difficult place to come and to come away with a point, we'll take that."
Asked if his side should have had a penalty for Randolph's first-half challenge on Ethan Ampadu, Ramsey added: "I don't know. It looked a bit clumsy but I don't know, I'll have to watch it back."
Wales manager Ryan Giggs admitted his team had struggled to get find their stride.
"It was a bit scrappy. We didn't really get into our rhythm - I think you've got to give credit to Ireland for that. They pressed us," he said. "I thought we started the second-half a lot better but then again it got a little bit scrappy, which suited Ireland more than us."
Asked if a point suited the Welsh better than the Irish, Giggs said: "Yes. Three games, three clean sheets, seven points, two away games, so you have to be happy,
"But our performances obviously need to get better and they will."
