There are plenty of other guns if we're discussing the notion of OP. Which of course puts the whole initial premise in doubt. Like others have said, people mistakenly consider something OP simply because it's popular. People originally complained about IB only consisting of the OP Suros when it was mostly a byproduct of the daily auto rifle headshot bounty. The Suros was never OP, just non-coincidentally popular. Bottom line: If you cannot beat a better player with a vendor legendary hand cannon, you will still not be able to beat them with a Thorn.
