Other than it being free, what is so special about it?
Oh my god, most guys saying "why do you need a bot etc", you're using bots yourselves, 90% of the 8.X community is botting and it seems to be natural to do so, heal bot is not a recommendation if you're going to war, it's an obligation.
That's why I stick to 7.X servers' where even the community dislike botters.
And from what I know, it's possible to source-edit without the actual sources; unsure of the name of that programming though. Might be called "Backwards compatiblity" not sure if it's that though.
