I can’t comment on the turbo, but I have had little issue with queuing around 6-10 GMT or weekends in EUW. Queue time averages around 1-3mins. I am normally playing with a 3-5 stack though if that effects anything.

well turbo games’ financials are completely different.

jungle camps are essentially worthless while kills give you more money. so your gameplay style, item build etc. should reflect that. tp cooldowns are shorter. one of the best items you can get early on is boots of travel. because you can join any fight and therefore get more gold (since again, kills are much more valuable in turbo). some teams in turbo focus too much on farming while their other lanes are getting killed. just one tp and you can swing the whole thing around. in regular games, kills in early on do not give you that much gold. the biggest benefit of an early game kill is usually the enemy team losing farm. but in turbo they can lead to snowballing like you said. but because of that same mechanism, comebacks are much easier in turbo as well. smoke with your team and get two kills and you’ll be back in action. honestly just don’t jungle and you win.

edit: I forgot to add. all of this stuff about gold applies to exp as well. enemy team is level 20 while you’re 14. one smoke kill and you’re the same level if not more

as for your que times question, I live in the US but have friends within Western eu so I frequently play weu games. usually we have no issue finding a game within 1-2 minutes. we play around 4 pm here so that’s 9 pm uk. weekdays are worse though obviously. I think Dota 2’s player base is older than most games and we all have jobs
