Well, I am of two opinions on this.
For one, when the bot was on, it was always more useful to have a !solo command on, as it'll be easier to actually "train" yourself and easier to get higher speed with no one else around. It was all around more convienient and fun with solo than without it.
On the contrary, I am one of those people who believe the bot shouldn't be overused, like some of the people I see on the server. They want to vote in the bot in maps that don't make any sense (like Redcourt or Champ). It gets really boring cause the bot is more likely to blast a rocket into the ceiling or low skybox than an actual human player would, and that lowers the fun of those maps for me if the bot were on those maps. Maps like Gallifrey, Horizon, Spacedout, maps with like a ginormous skybox, I'm all for using the bot for. These newer players who didn't play on Chronic need to understand this quicker or else, yes, I agree with Jake (Protocol) that impending doom is incoming for a few players, including myself.
