The Infinity guide is the most infamous example.
ON TVHM he killed Mercy in such a way that you couldn’t see any any of his drops. When he went to check on it a Level 50 Infinity was lying there, standing perfectly upright.
Problem is, the video was uploaded on Dec. 1st, 2012, long before the patch that fixed his drop rate in TVHM (and UVHM).
There was no mention of that broken drop rate in the video whatsoever, only that it could take a very long time, which is technically true but we are talking about a chance that is less than 0.0001% so he gave false hope to many players who wanted to get an Infinity themselves.
That’s all I am going to say on the matter.
