Yes, it was on purpose with good reason. It is a lot easier to kill the bots on easy. Maybe they will make it so you have to kill many bots to get one kill. Maybe less kills for the more difficult settings. Maybe they'll think of something different or maybe they'll leave it like it is. Whatever the case, I think there's more important things to work out first, like why is Breakthrough not loading properly most of the time? It's absolutely infuriating.
I think the solution should be that anything you unlock in solo/coop will remain only usable in solo/coop. See many of us only ever want to play solo/coop. Meaning, it is more fun to my friends and I (and better use of limited time) to get on a server and play as a team to take out bots. If this approach is done, then the easier kills from bots wont affect the integrity of those players who are really good on human servers.
