Until Cryptic builds in functionality that lets a person set up a private arena/scenario with optional rules/restrictions, this is completely subjective and on the honor system. Until Cryptic builds in a functional tournament system with ranks and a leaderboard, the whole idea is pretty much meaningless. In my opinion.
When you can actually apply optional rules to a PvP scenario, then tournament restrictions will be meaningful, enforceable, and non-negotiable. Rules like "Sudden_Death" (No respawn), "Disable_Placate/Confuse", "Disable_C-Store_Consoles", "Escorts_Only", "VA_Only", "No_Lockbox_Ships", and more.
Better yet, a "Tournament Mode" that automatically applies a set of standard rules to a PvP scenario and puts everybody on a "level" playing field automatically.
In that scenario, there's nothing stopping you from equipping "cheese" except for the fact that it's disabled and you're gimping yourself by doing it.
Even though this idea is not new, it would be awesome - There is one downside right now though. We don't have the numbers in pvp to allow this to happen. However if we got the numbers and got this feature I'd be a STO slave for life
