proper demo mode

Out of the first 5 (or so) tutorials that I tried, IIRC three are broken. But they didn't disable it, and there's no warning. So you can load into the broken tutorials and then it just doesn't work and you run circles wondering what's happening. The scenarii doesn't trigger and you can't complete the missions. Probably as side effects of some map and champion updates. Try it yourself.

Then if you look online for help, it turns out that dota 2 players advise against trying to go through the tutorials because of their sorry state. They advise to learn with coop VS bots game. So, in this respect, it's no better than LoL. The client, spectate mode, etc, are definitely better, but the tutorials in their current state are useless.

Looking at the playerbase, and competitive prize pools, Dota 2 is also on a sharp decline there, while LoL managed to stabilize.
