I've had games turn around enough times and I have also turned around games enough to make the OT exciting.
But it does absolutely need a time limit.
Maybe start spawning the field mechanics more often at an increasing pace until people just get KOed more often that'll result in both teams just falling over so the currently dominant team would get the win after like 2 mins of OT.
And for the map without field hazards perhaps just drop Odin down and he slow casts Zantetsuken or something lol.
