If you don't appreciate grappling, stalling and the boring aspects of a fight then you are a moron and not a real fan.
Of course we all want entertaining fights but you are delusional and spoiled if you think you deserve nothing but excitement at all times. Fighters need too save their cardio and win fights how they can against dangerous opponents because losses effect their health, pay, popularity and legacy. Some fighters might be boring but if they are winning then they are going to be used and going to be given championship opportunities and deservedly so.
