Just bought HB. Using BGBuddy and it seems clunkky but none the less it works. Can I only bot for a couple hours then I have to get off? I wanna bot for like 4~6 hours and then maybe switch characters or something. So my question is, is it more likely for me to get banned if I switch characters and bot some leveling on him or ?
You are more likely to be banned for playing same character. However, if you play 4-6hours by yourself then it won't matter if you bot for the same time. Just make sure you are not following a default profile and default class routines.
My personal advice for you is don't use BGBuddy, it is the absolute best way to get banned as of right now. Get yourself a nice routine and use it with Lazyraider/tyrael.
