Trinity Caverns: I played a game recently on this map, I went second and one of my guardians was killed before my first turn. I ended up winning that game anyway, but it was not nice to be unable to prevent that in any way. At least my opponent had to sprint and to expose himself, so maybe it can be considered a high risk/high reward maneuver, I will keep an eye on this map.
Infernus: I have to agree on this one, if you start top left and your opponent is bottom right you can unload spells on his top guardian and then sprint to safety, that is basically free damage with 0 risks that he can't avoid.
Perilous Waste: I don't love this map either, but at least it is the same situation for both teams. You really want to play the wizard here
