Honestly I’m the same way. If I’m soloing I’m mostly reading the forums with my controller tabbing back and forth, reading my discord chat messages from friends, tabbing back into my computer program I’m writing and all kinds of other things. Since Tree of Savior is really a solo-fest I don’t pay much attention to any chat going on at all in it.
Best way to determine if it’s a bot or not is to watch it. Bot behavior in this game isn’t even sophisticated seriously… the bots are so fricken obvious compared to actual human players.
