Exactly! I agree 100 percent. I just got done explaining to another user how I don't usually play multiplayer games and thus don't like being in the position that stands out the most, the character whose every action and every mistake is monitored by all the other players in the game. It's difficult to get good as a killer in this game without feeling like an idiot. A killer practice mode wouldn't be a full replication of what it's like to go against experienced humans, of course, but it WOULD provide players with a venue in which to practice their powers, timing, various strategies, etc. The AI of the basic bot mode as it currently exists is actually pretty good, honestly reasonably lifelike, so to be able to choose the survivor or killer (as well as their perks) would be a great way for people to gain valuable experience without having to worry about feeling foolish or being decimated by other players.

There would be so many possibilities with a fully customizable bot mode. Even that roulette concept - an option to fully randomize EVERYTHING - would encourage the player to try new characters and new perk builds. It could be such a handy mode. The bot matches have gotten positive feedback so here's hoping that they aren't forgotten amidst the update glitches.
