Better Bot AI and Coop vs AI matches.
I'm slowly coming to figure out that a large part of my problem with playing PVP matches is that I can not have fun unless I'm winning. Maybe that's because winning is such a concrete thing declared by "Victory" or "Defeat" right in front of my face and also because I am at the mercy of too many external things (other people/team comp). That said, bot matches seem like a possible compromise since they can adjust for a player who goes afk, etc, making me less at the whim of forces I can't control and putting control of the loss or victory in my own hands rather than teammates. The one problem I frequently observe is that players who are TOO good end up joining the bot matches and massacring them solo while leaving little to nothing meaningful for me to do. I request that Riot make better bot AI and perhaps tweaks to improve the PVE experience of people like me who aren't good in PVP and have a difficult time being sportsmanlike in the lopsided feast-or-famine matches you've created in all the previous patches.
As far as I see it, this is win-win. You keep me out of PVP matches, hypothetically making the experience better for other players and I get to play the game in a mode that's better suited to me. As a paid customer, I don't think it's unfair to ask.
