because strats matter A LOT.
paragons ragnaros tactics handling the seeds to aoe them down rather than spread out and kill 1 by 1 was much better than methods, one of the reasons they won.
and it was methods weak aura in archimonde? that was much better than the way paragon handled the beams and gave them a big advantage to win that.
yes things like do make a huge difference, giving away things like this could have easily swung the world first.
only difference with Uldir is i don't think it had such crazy required tactics like the above 2 examples, Uldir was simply a dps/hps check over and over.
