The ´´problem´´ here is that you´re not used to lose against a warlock .. you´re used to lose against frost mages , as a warrior .
On this map the warlock can use his teleports at his best , killing you, but how is it on other maps where he can´t teleport up somewhere ? are you still complaining ? of course not because you kill the warlock easily ..
So yeah .. in this case the map is in warlock´s favor .
