> Because our training system Rapid is very general, we were able to teach OpenAI Five many complex skills since June simply by integrating new features and randomizations. Many people pointed out that wards and Roshan were particularly important to include — and now we’ve done so. We’ve also increased the hero pool to 18 heroes. Many commenters thought these improvements would take another year.

The linked commenters thought that getting to "real dota" (more than 100 heroes, captains mode instead of random, ...) would take another year. So I don't think it's fair to make that statement.

Edit: Don't get me wrong, I think the improvements are very nice, but pointing to people saying "these people thought we would need a year, we did it in under a month!" is not what you should do if you didn't actually do what the linked people stated.

It seems like the 5 invulnerable couriers restriction is something that will have a huge influence on how the early game is played and is something that the humans won't have any experience taking advantage of.

I don't think it's that complicated to adapt to... everyone should just be pretty much constantly ferrying out regen and harass more aggressively.

people play with 5x invulnerable couriers in turbo mode. Essentially that is what they do. They get their items asap.

And bottles are currently disabled so you can't use the most abusive strat that 5 couriers would allow.

You can't. It was changed around this year.

Courier isn't that important. It's being phased out across the recant patches. And there is a popular Dota mod with 5 fast invulnerable couriers.
