My oppinion
Minus sides
Ofcourse, there are only a few minus sides I can see in botting and they are obvious to everyone. First, theres no real thrill or happiness when playing on a botted account. Then there's the risk of getting banned, meaning you risk your account (just like walking over the rope in the RS D&D circus...). It usualy is annoying when training legitly see over 20 people cutting your yew tree (17 of them are bots), you can't enjoy the game as it is desired by jagex.However, every bad thing has bonus sides so i'll also post them here.
Bonuses of botting
When botting, you save precious time (e.g. time for studies,work etc.),when botting you can make money for real not pixel things such as daily needs for lunch,weed and more. Botting also boosts up the economy to a deceantly needed level.
In my oppinion it DOES defeat the purpose of the game, i have played legitly since 2003, never botted,slowly enjoying my game, and now everyone should try to play the game for joy. I'd say playing legitly only makes it more fun.
