The keyword here being “can”
You ask why stalemates are possible and feel as if you have been betrayed by CCP because of their own words and description yet you fail to acknowledge that nowhere in your original post does CCP ever state two will enter but only one will leave - they state verbatim that "two enter but only one CAN leave. No one was ever promised or given the expectation to believe that they will be able to leave for sure, only that the possibility exists for them to be able to leave.
Now to be fair this is an older thread and I have not read the entire thread, only the original post by the OP - there have been nerfs, buffs, and changes since this original post, but it’s this original post to which I am replying to and nothing in the timeline after. Thanks, and cheers
