It can be rough especially at the lighter weights (such as WBW UT lol)
Personally I think your strategy changes depending on length of fight.
* 5 rounds --- LET HIM GAS --- let him chase you and throw tons of strikes while you make him miss. Work the Body. Take him down. Frustrate him and DRAIN HIS STAMINA --- you can pretty much give away the first 2 rounds if you have to. By round 3 he's gonna be gassed, time to fight back. You have to win round 3!
* 3 rounds --- you're gonna have to try and fight fire with fire to some extent. You don't have time to wait out his stamina. Which is a shame...like you said, in these examples, their stamina should be drain MUCH more quickly!!!
Anyway, my suggestion in a 3 rounder is to either make it 100% Grappling --- or just try to counter with big haymakers the best you can.
In a 5 rounder it's pretty easy to beat these bums.
3 rounder can be tough. If you try to slug it out with them they can catch you. If you try to play defense, they will outpoint you with volume alone.
but I agree, we need more stamina drain in this game especially for ridiculous volume of strikes (and on the ground!!! so you could drag them to the ground and sap their strenght!! --- to be honest, to drain opponent's. stamina, you want to keep the fight standing almost no matter what. Which is dumb. We need more permastam drain on ground and in clinch
)
good luck ---------
