I voted yes, but honestly they both have their pros and cons.
Without botting: You enjoy the game the way it is meant to be. I think this game is boring most of the time, so I have to admit I do bot sometimes (When I used to play). There are a lot of people that actually like the game and play legibly though. I enjoyed the game much better back in 2007.
With botting: Get a high level stats and dominate, but there are a lot of people with the same intention so it may get boring and not as awesome as it was a few years ago to reach a high milestone.
