When i searched DotA 2 in outdated versions until 7.19 where was available offline mode available, so Why Valve removed offline mode in 7.19b patch. While i attempted play Practice with bots in offline mode, but game crash. I know Practice with bots in offline mode don't working, but in May 2021 i connected to Internet to play Practice with bots mode.
Topic on Talk:Dota 2
This is not the place to complain about changes to Dota 2. In fact, PCGamingWiki lacks the connections to even forward such a complaint to the appropriate people within Valve. As such, complaints not connected to the article - which this is not - will go nowhere.
1. You can play vs bots (solo) and demo heroes offline. 2. This wiki has no relation with Valve, complaining here won't do anything. Complain there instead: https://github.com/ValveSoftware/Dota2-Gameplay/issues 3. Please, don't use the caps lock. Also, you might need this: https://www.grammarly.com/
I tested in Source 1 version and working offline mode. But until 7.10 in Source 2 version i can play offline mode...
You probably wanted to post this in the forum instead.
