It's not really a problem I would say. They merged a fuckton of servers, and regions, so theres no more EUW and EUC with 15 and 10 servers respectively, but everything is merged into 5 servers now. I think the NA/SA servers were merged in a similar way.
Bots come and go, sometimes prices of fish and other shit goes down, so you notice bots have made a bit of return, but from what I've been told, it's barely noticeable at this point. You can definitely play the game without having to worry about bots, I know I am.
