Co-op recomendation

Hey guys,
Me and my friend like to play co op games together. Just need some recomendations.
We started playing CSGO for a while, but he lives in Dubai, and me in Australia, so the ping makes it hard.
Then we moved on to division, but in a week we were both maximum level, got all the intels, etc. Then "The Crew" went free, and we played that for a few days, but we are again maximum level, and all missions finished, hidden cars unlocked, all locations discovered, and find ourselves getting bored. We already played portal 2 before, and finished it in 1 sitting. I just bought Splintercell Blacklist keys so we can play that for a little bit. But I have no idea what else to get.

Games we didn't like :
Sanctum 2
Payday 2 (It wasent bad.. we just wanted a 4 man, which didnt work out)
He isnt a big fan of puzzle games, though he enjoyed Portal 2
Probably no ARPGs like Path of Exile
Games like Battlefield and CoD are hard to play with such a ping difference.

Edit: Thanks a lot for the recommendation guys. I think a few of them are something me and my friend can explore. Sorry, I cant reply to each and every comment, but you guys have been a great help.
