Arena of death by Waldo the Swede (and uhm, not Caia, not by a long shot)*(-1). Why I have to nominate Mercury again is beyond me. Amazingly droll, troll.
In addition to my previous nomination of Arena of Death by Waldo, I will add: Vertigo by Remember Isao24 This map is a very refreshing 2v2s map that brings a perfect amount of verticality to the table.
Also, Caia by Longshot. And yes, that is the first time I've actually found more than one map worth nominating for an FHF in months.
