This, pretty much.
"Just be the superior team", while not untrue advice, isn't helpful advice. Pld cheese aside, all teams generally want to be the better team at killing. And it happens just as often as not that the teams that do a good job at killing also happen to cheese, because they're not really correlated. If between 2-5 people focus on the cheesing and the rest of the team just play normally and do a good job of killing, you have a team that goes full ham on cheese, and also dominates BH.
So "simply focus on kills" isn't something that's going to cut it in many cases.
The stereotypical cheese scenario also isn't a paladin and partner openly running all alone up to the ovoo with nobody else around for miles, suicidally declaring their intent to abuse.
In the majority of cases there's a huge, vibrating ball of squirming limbs and fireworks thrashing its way towards the ovoo from 2 or 3 directions, and then from the chaos, the cheese emerges, already in full motion.
And no. I'm not going to hang back, and scan the entire crowd looking specifically for paladins, and then attempt to wade through the entire enemy front line in order to cut them off.
Which is why I don't go to Onsal anymore. It may be the way things are supposed to be done nowadays, but I think it's an idiotic idea that such is the case.
