Mod†Mat†Ksaid: Reading through the comments, it seems a lot of you are upset about the cost of steam battlestaff plummeting (if it of course does that). Perhaps we should look at ways to improve it to help it hold its value.
Except that using OSBuddy doesn't give you an unfair advantage towards Runescape. Everyone has access to it. Everyone always will have access to it. Your argument is similar to one a sober man once said;
"Drinking alcohol is the worst any man can do, and I will never do it!", in which the drunk man replied, "Too bad sonny, you're missing out".
Instead of complaining about all the people who, implied by you, are getting an unfair advantage by using this client, why not go use it yourself and see how much better it is?
And on the topic of splashing, it was never designed to be implemented into the game, it was a repercussion of a previous patch, that is now being removed from the game.
There are so many problems with your post, but I'll name just a few for starters.
-I don't recall 3rd party clients ever being officially added by Jagex. -Anything that 3rd party clients provide that the official client cannot are advantages. -Everyone potentially having access to these clients does not justify their use; ie. splashing/afk
