That is subjective. In case you have fun leveling and do not care about the health of the game. Wasting your time to grief bots will not help you in classic wow gold any way. Again though this post is about gaining xp out of griefing bots so that it's a win / win win for everybody.
I did so with a bot at stranglethorn for a fantastic hour. Tag his telescope, label another mob, kill that while he kills my other and then head to the next!
Once the bot is completely automatic and grinds mobs for 24 hours, you sticking around and tagging his dinosaurs for a single hour regrettably means nothing.
Did this in my Shaman using a mage bot leveling in STV. Farmed 3-4 Golden pearls and a couple of levels for me. It was a fantastic couple of hours while it lasted.This method actually ends up slowing down you till you help it using the kill.
OR go to hillsbrad at which the mob density is higher, and then you can kill another mob while the bot kills the one which you tagged.(https://feedsportal.com/world-of-warcraft-how-this-game-is-a-classic/)
I've definitely done the latter. It's a modest XP/hr increase, and because the bot follows a set route around the corner (except if it sees a mob), doing so helps hasten it out of your area of the map.
Also, if you farm spiders near Dun Garok you can get big venom sacs and bruiseweed, which are used for elixir of toxin resistance. Quite profitable if you were going to be buy gold classic wow grinding anyhow.Did this at Burning Steppes when I leveled a warrior onto a new server. Couldn't solo the elite dragons for ony however there was a bot hunter there killing them. Worked out well.
