No real reason i just like trying new things and if there is a better build out there, why not? I don't do afk farming i tend to invite a few ppl here and there to help them out as was done for me when i came back to game over a year ago, and yes to farm inf. always helps me and my wife (who doesn't farm) who is constantly making new characters and they all have to have TT, ATT, and MT lol. She is not what you would call a cheap teammate.
