The main thing (which unfortunately most Smogon players do not understand, albeith I saw some mention it), is that Smogon per se is trying to play a game with rules that the game is not made about.
It's like if you're trying to play soccer with 4 goalkeepers, or Rugby with 3 balls. Sure you "can" play it, but the rules and field were not made with the intention of that interaction, and ofc it does become a mess.
Since a few generations, GameFreaks has been focusing intensely over VGC and making Pokemon a "esports" (memes included).
E-sports however require to be interesting to watch. One of the main reason for the presence of such high impact mechanics like Dynamax and Terastal, and decent variance with secondary effects, is because these create spectator interest. As much as it would be interesting to play a calculated match of chess where all that matters is player decision and everyone is on even field, in reality the tension generated by a crit or freeze at a weird moment is much higher and the hype behind surprise comebacks is massive when it comes to spectatorship.
In same way, they always try to nuke any type of stall strategy (see matches having strict timer and recovery nerf) because these matches are just not fun to watch.
Do note that it's a pretty weird misconception that VGC is "all ho with broken pokemon". In fact, it's a very calculated metagame, and while matches are indeed often over in few turns, most pokemon do invest in bulk and positioning is as important as ever, specifically because you only have 4 mons and losing even a single one can be match deciding.
Es this was one of the latest top 10

You'd expect everyone playing ChienPao / ChiYou / Fluttermane / Bundle / etc etc, yet.... most teams actually play bulky offense and there's even Yvar playing cursed stall (pls stop)
